Chicago-Latrobe 48525 Screw Machine Drill Bit
This Chicago-Latrobe 48525 is a screw machine drill bit with a 25/64 in diameter and a 118-degree conventional point. It is made from high speed steel with a bright, uncoated finish. The bit features a right-hand cutting direction and a decimal equivalent of .3906. It suits machinists and technicians needing a standard general-purpose bit.
Bright uncoated high speed steel construction
The bright finish leaves the high speed steel surface uncoated for conventional drilling tasks. The 118-degree point angle provides a standard geometry for general-purpose use in a variety of materials. Right-hand cutting direction matches common machine tool rotation. The non-coolant-through design suits standard external cooling setups.
Machinists needing standard 25/64 in HSS bits
This bit fits workshops requiring a 25/64 in high speed steel drill with a conventional 118-degree point for screw machine applications. Buyers who need a coated bit for extended tool life in abrasive materials should look elsewhere. Those requiring a coolant-through design for deep-hole drilling or a different point angle for specialised materials will need another solution. The item is restricted from sale in certain states.

Questions about this item
When will the 25/64 inch high speed steel bit need replacement?
The high speed steel construction wears gradually; replace the bit when the cutting edges no longer produce clean holes at the 0.3906 inch diameter.
What limits continuous drilling with the 118 degree conventional point?
The bright uncoated surface generates heat faster than coated bits, so sustained cutting speed drops once the tip temperature softens the steel.
How much heat and noise does the right hand cutting direction produce during all day use?
The uncoated high speed steel transfers more heat to the workpiece and creates typical drilling noise; no coolant-through design means heat builds in the bit itself.
