Walter Prentice Drill 1in 6in
The Walter SST+ Prentice drill bit is a heavy-duty large-diameter cutting tool built for portable drills, drill presses and magnetic-base drills with a half-inch chuck. Its cobalt blend and extra-hard tips extend service life between re-sharpenings. The 135-degree point geometry removes the need for pre-drilling. Three flats on the shank stop slippage inside the chuck.
Metalworkers needing fast large holes
This bit suits fabricators and maintenance crews drilling mild steel, non-ferrous metals and stainless steel in a single pass. It is not for wood, plastics or masonry. Users without a half-inch chuck or a rigid magnetic-base drill should look elsewhere. The bronze SST treatment targets metal-cutting heat, so other materials gain no benefit.
1in diameter 3-1/8in flute 6in length
The 1-inch diameter and 3-1/8-inch flute cleanly clear chips in thick plate and structural sections. The 6-inch overall length reaches through flanges and gussets without an extension. Cobalt hardness keeps the edge sharp across many holes in stainless steel. Very deep holes beyond the flute length will need a longer bit or peck-drilling cycles.
Highlights
- Drills more holes faster with cobalt blend construction

Questions about this item
Will the 1in diameter shank fit my drill press with a ½in chuck?
The 1in diameter drill bit has a ½in shank with three flats, so it fits any portable drill, drill press or magnetic base drill that accepts a ½in chuck.
Can I use this cobalt blend bit on the mild steel and stainless steel I already machine?
Yes, the bit is designed for mild steel, non-ferrous metals and stainless steel, so it will cut the materials you currently work with.
How do I know the 135deg point geometry is cutting correctly after I start drilling?
The exclusive point geometry eliminates the need for pre-drilling; clean, fast chip formation and steady feed without wandering indicate it is working as intended.
