Cle-Line 1876 31/64 Inch Drill Bit
The Cle-Line 1876 is a reduced-shank drill bit with a 31/64 inch diameter and a 135-degree point angle. It is made from high-speed steel with a black and gold finish for general machining tasks. The fractional inch measurement system applies. This accessory fits standard drill chucks.
Best for Machining with Fractional Sizes
Machinists who need a 31/64 inch high-speed steel bit with a 135-degree point will find this suitable. The reduced shank allows use in chucks that cannot accept a full-size shank. Buyers needing metric dimensions or a different point angle should look elsewhere. This bit is not designed for non-machining applications.
Capacity and Headroom in Machining
The 31/64 inch diameter handles holes of that specific fractional size in typical machining materials. The .4844 decimal equivalent provides a reference for precision work. The high-speed steel construction supports standard drilling speeds. The bit runs out when a larger diameter, a different material, or a non-fractional size is required.

Questions about this item
Does my drill chuck need to open wider than 0.4844 in to hold the 31/64 in bit?
Yes, the shank diameter is 0.4844 in, so the chuck must accept at least that size.
Can I use the Cle-Line 1876 bit in a 3/8 in chuck drill I already own?
No, the shank is larger than 3/8 in, so it will not fit that chuck.
How do I confirm the 135 degree point is cutting correctly after I start drilling?
The bit should self-centre without a pilot hole and produce short, curled chips in steel.
