Walter 01M550 Prentice Drill Bit
This 23/32 inch cobalt blend bit fits portable drills, drill presses and magnetic base drills with a 1/2 inch chuck. The 135 degree point geometry removes the need for pre-drilling in mild steel, non-ferrous metal and stainless steel.
Three flats on the shank stop slippage inside
Align the flats with the chuck jaws and tighten firmly to prevent spin-out. The 6 inch overall length demands steady pressure; forcing the feed on thick plate can overheat the tip despite the SST treatment.
3-1/8 inch flute length sets the practical depth
The bit clears chips efficiently through that flute length in mild steel and stainless. Deeper holes require Peck drilling to avoid packing. The cobalt blend extends life but the diameter is fixed at 23/32 inch for larger requirements.

Questions about this item
How can I confirm the 135° point geometry is cutting cleanly without pre-drilling?
The 135° split-point design starts on contact and the three flats on the shank prevent chuck slippage, so clean entry holes in mild steel, stainless steel or non-ferrous metal show it is working as intended.
What comes in the box and do I need a separate chuck adapter?
The package contains the single 23/32" diameter Prentice drill bit with a ½" shank; no adapter is required if your drill, drill press or magnetic base drill has a ½" chuck capacity.
Which diameter should I choose if I need the 23/32" size?
This model is the 23/32" diameter version with a 3-1/8" flute length and 6" overall length; select it when your hole size matches that exact diameter.
