Cle-Line C18657 31/64 in Drill Bit
This Cle-Line jobber-length drill bit measures 31/64 inch with a 135-degree split point. It is made from high-speed steel with a TiN coating for general-purpose drilling. The decimal equivalent is .4844 inch. It suits maintenance, fabrication and automotive tasks where a fractional size is required.
Suited for fractional-inch drilling in steel
Machinists and technicians who need a 31/64 inch hole in ferrous materials will find this bit matches the specification. It is not for coolant-through operations because the design has zero coolant holes. Buyers who require a different diameter, a different point angle or through-coolant capability should select another tool.
31/64 inch diameter with 135-degree split point
The single specification that decides fit is the 31/64 inch diameter combined with a 135-degree split point. This exact size and geometry must match the hole requirement and the material being drilled. Verify the fractional size and point angle against the job specification before purchase.

Questions about this item
Should I choose the 31/64 in size or a different fraction for my application?
Select the 31/64 in bit when the hole must be exactly .4844 in decimal equivalent; choose another fraction only if the drawing specifies a different diameter.
What does the 135 degree point angle do once the bit is in the drill?
The 135 degree split point centres itself on contact and reduces walking, so it starts cutting faster in hard materials.
How does the straight shank interface limit use in practice?
The straight shank fits any standard three-jaw chuck but cannot be used in taper-only or SDS holders without an adapter.
