B: Warning:
Auger Bit:
Always read and follow the operating and safety instructions in the power tool owner\\\'s manual and the instructions for use of the accessory. Always wear safety goggles to protect your eyes, gloves to protect your hands, and wear other appropriate safety items for protection. Do not drill near live electrical circuits. Do not use a side-to-side movement when drilling. Make sure the backside of the material being drilled is clear of wires, cables, pipes, and other objects that might cause hazards. Do not operate in excess of 2,500 RPMs.
 
Drill Bit Extension
Always read and follow the owner\\\'s manual for your power tool and the instructions for use of the accessory. Always wear safety goggles to protect your eyes, and wear other appropriate safety items for protection. Always inspect the bit and the extension prior to use, and do not use them if damage is suspected. Do not use the bit extension in gas or impact power drills. High torque loads from these drills may cause the extension to break, which could cause bodily injury. Only use grooved hex shank accessories with the extension. Non-grooved hex shank accessories will not lock into the extension, and could unexpectedly release while drilling, which may result in bodily injury.
 
C: How to resharpen King Drill  auger bits?
First never sharpen the  outside edges of the bit that cut--the spur and side lip. There are three  edges you may have to sharpen--the spur, cutter and side lip. Your bit may  not have a spur. The spur is a thin piece of metal that sticks up parallel  with the screw point above the cutter. To sharpen it hold  the bit by the shank or twist against a work bench. Using a flat file,  sharpen on the front (as you view the cutting edge) and top inside edge of  the spur. Never sharpen the outside. To sharpen the cutter and side lip, hold  the bit upside down with the screw point sticking into a piece of wood. This  gives you a clear view and access to the underside of the cutter and inside  of the side lip. Using a small triangular or square file, sharpen the  underside of the cutter and inside the side lip.
