C29R10 is a set of 29 jobber drill bits in a sturdy case. The 29 R10 fractional drill bits in the set are manufactured from High Speed Steel and can be used for drilling many materials including steel, stainless steel and aluminum. They range in size from 1/16” to 1/2" in incremental sizes of 1/64”. The steam oxide finish prevents workpiece material from sticking to the cutting surfaces of the tool for a clean and accurate result, whilst the strong conventional 118 degree point is easy to re-grind so the drills can be sharpened and re-use many times. The R10 drills in the C29R10 set are suitable for drilling in many different applications, both by machine and hand-held, making this a very versatile choice
