thirty-seconds to 1/2 inch the model 750 X Chuck will sharpen bits up to 3/4 inch in size this Chuck may be purchased separately for the model 500 X your model 500 X or 750 X can sharpen split point bits and you can control the point angle and the relief angle of the bit and you can even sharpen left-handed or reverse twist bits if you purchased a special chuck your drill doctor is constructed around a metal core for precise sharpening and splitting stay tuned to learn how to use your drill doctor to keep your bits factory shape hi i'm robert gilman the drill doctor is no ordinary tool it's a professional quality drill bit sharpener used by small manufacturers machinists and mechanics worldwide I'm here today because a few simple demonstrations well if you quickly master your drill doctor but first it's important to understand how a drill bit works these are the flutes they don't cut they just move material out of the hole the cutting happens at the tip of the bed with the chisel point and the cutting edges the keys to a sharp bit are easy to see on this industrial drill the chisel point must be absolutely centered the angle between the chisel point in the cutting edge must be right the cutting edge must be sharp and there must be a downward angle away from the cutting edge the drill doctor has an innovative design that creates this geometry it starts with patented dual cams that move the bit in two directions in and out up and down creating exactly the same motion factories used to make new drill bits the drill doctor uses an industrial-strength diamond sharpening wheel so that hundreds of bits can be sharpened without the wheel wearing down or changing shape with your drill doctor you have the option to split the point of the bit over the past 15 years a modified drill bit called a split point has become popular the bits with this feature may also be called high-performance or back cut bits to create a split point after sharpening a small amount of material is taken off of the backside of each face of the bit this narrows the chisel point so the bit digs into material faster and they wander less so you rarely need to centre punch holes split point bits can be particularly useful when drilling into metal bits made from specialty materials like cobalt and carbide work best when they have these points drill doctor not only lets you maintain the split point bits you own you can also add a split point to any of your other bits sharpening with advanced features most drill bits have a standard 118 degree angle however when drilling into certain difficult materials a shallower point or a 135 degree point angle produces a better finished hole your drill doctor allows you to sharpen bits with either the standard 118 degree or the flatter 135 degree point angle you can also adjust the relief angle now this is the angle at which the surface of a drill bit falls away from a cutting edge depending on the material you are drilling you may choose to increase or decrease this angle if you purchased the model 750 your drill doctor has additional advanced features that fine-tune your bit geometry these include a wider range of point angles and adjusting how much of the bit tip is removed when sharpening consult your user guide to learn more keep watching to learn how to get the most out of your drill doctor and thank you for buying the drill doctor we think you'll be glad you did stay tuned the following tape includes sharpening demonstrations a tour of the parts that make your drill doctor work specific

split the point of the bit that's all there is to sharpening bits with drill doctor a tour of the drill doctor the key parts to the drill doctor are the chuck the alignment port the sharpening port and the splitting port this is the chuck these are the alignment guides the Chuck jaws that hold the bit the chuck nob that tightens the chuck the chuck cams that create the sharpening motion the sharpening guides for the white lines for sharpening and the marks for aligning the masonry bit now look at the alignment point these are the alignment notches with a 118 degree marking these are the clamp arms this is the drill stop and this is the alignment button when pushed in it opens the clamp arms this is the sharpening port this is the cam guide note how the sharpening tube rocks back and forth and this is the diamond sharpening wheel this is the nob you loosened to adjust the point ankle to a standard 118 degrees or a flatter 135 degrees this is the metal splitting forth these are the guide rails and this is the mark for aligning the chuck this is the grip tube to prevent sparks from leaving the drill doctor this is the cover you will move to replace the sharpening wheel this is the material take-off adjustment knob detailed demonstrations before sharpening you should ensure that the point angle is set correctly set it to either a standard 118 degree or a flatter 135 degree point angle in this example we will use the 118 degrees setting if you have a model 750 X you will need to adjust the material takeoff nob before you begin to set turn the knob counterclockwise until it stops then turn clockwise three marks on the nob this is a good place to start for most bits step one alignment insert the bit into the Chuck jaws and close the jaws just to the point where the bits slides in and out press the alignment button down and hold it insert the Chuck and match the alignment guide on the chuck with a 118 degree notch on the tube release the alignment button and make sure the bit is touching the drill stop look at your bit and make sure the clap arms are in the bits narrow a spot if they aren't turn the bit to the point that is held by the clap arms in the narrowest width this is important because this setting determines the angle at which your bit is sharpened then hold on to the Chuck and tighten the Chuck knob for us the alignment button and remove the Chuck drill bit tighten the Chuck once more so that the bit won't move when you sharpen it consult your users guide for additional alignment settings step two sharpen insert the Chuck and align either white line with a cam guide now rotate the Chuck 1/2 turn in a clockwise motion turn white line to white line an even number of times about six half turns for a quarter-inch bed and sixteen to twenty turns for a 3/8 inch bit remove the Chuck and inspect the bit listen carefully to the sound your drill doctor makes note that you should direct light pressure into the sharpening hole not down and always make sure that the Chuck rests firmly against the cam guide as you turn the Chuck this causes the sharpening port to rock back and forth and shapes your bid for the best cutting optional step split the point to split the point do not remove the bit from the Chuck after sharpening align the white line on the Chuck with the mark on the splitting port this will line up the alignment guide with the guide rails press chuck slowly and firmly into the splitting port until the Chuck stops rotate one half turn and repeat a correctly split bit should look like this sharpening small bits a few quick pointers will help you sharpen smaller bits more successfully to align the bit put the bit in the chunk so that it's just snug enough for the bit to move freely press and hold the alignment button and insert the Chuck part of the way use the chuck to rotate the bit until the clamp arms can hold it in the narrowest width of the bit release the alignment button and make sure the clamp arms are holding the bit in the narrowest width rotate the chuck until the alignment guide is at the 118 degrees setting push the Chuck all the way into the port tighten the Chuck remove and tighten again now sharpen the small bit but use very light pressure using an even number of turns the bit should only briefly contact the wheel sharpening large bits the model 500x sharpens bits from three thirty-seconds to 1/2 inch the model 750 X sharpens bits up to 3/4 inch in size this chuck may be purchased separately for the model 500 X large bits are sharpened just like any other bit it is important that the entire face of the drill bit is sharpened a large bit will require more white line to white line rotations bits 1/2 inch or larger will need a minimum of 20 1/2 turns a 3/4 inch bit may require up to 40 half turns your drill doctor is delivered with a 180 grit diamond sharpening wheel if you regularly sharpen larger bits between 1/2 inch and 3/4 inch you may wish to purchase the coarser 100 grit sharpening wheel which sharpens larger bits faster either the 100 grit wheel or a replacement 180 grit wheel may be purchased directly from drill doctor sharpening masonry bits masonry bits are sharpened using a plunge action insert the bit into the Chuck and line up the tip of the bit so that it's parallel to the marks on the end of the chuck set the depth by lining up the white line with a cam guide insert the Chuck then push the bit in until it stops tighten the Chuck remove and tighten again to sharpen line up the white line on the chuck with a cam guide then push or plunge the chuck until it touches the wheel rotate one half turn and repeat plunge action inspect the bit and continue until the cutting surfaces are sharp cleaning your drill doctor is a precision tool and should be cleaned periodically to remove dust and grit that can wear down the ports and the Chuck's the following process takes approximately five minutes and should be done after every 20 bits you sharpen you will need to clean the chuck the alignment port sharpening wheel area the sharpening port and the splitting port unplug your drill doctor before beginning the cleaning process to clean around the sharpening wheel use a dry brush to remove dust particles from around the wheel to clean the ports wipe the inside and outside of each with a dry cloth to remove any grinding dust or vacuum each port with a one inch vacuum hose a clean Chuck will prevent bits from slipping out of alignment during sharpening to clean blow compressed air through the Chuck from the nob end to remove grinding dust your diamond sharpening wheel will wear down over time and will need to be replaced to change the wheel remove the cover remove the wheel and replace add drill doctor we want to ensure that you are fully satisfied with your product consult your user's guide and our website for additional information and contact numbers thank you for buying the drill doctor
