31/64 Inch 135° Jobber Drill Bit
The Cle-Line C23152 is a high-speed steel jobber length drill bit with a 135-degree split point. Black oxide finish provides corrosion resistance and reduces friction during drilling. The fractional size measures 0.4844 inches decimal equivalent. It is designed for general-purpose metal drilling applications.
Suited for machinists needing a split-point bit
The split point design allows for easier starting without a centre punch, suiting machinists and maintenance technicians. Black oxide coating helps when drilling ferrous metals like steel and iron. Buyers requiring coolant-through capability or a different point angle should look at other options.
31/64 inch fractional size decides fit
The drill bit diameter is fixed at 31/64 inch with a decimal equivalent of .4844. This specific size determines whether the bit matches the required hole diameter for tapping or clearance. Verify the exact fractional size against your engineering drawing before purchase.

Questions about this item
Will the 135-degree split point stay sharp when drilling 31/64 in holes in steel all day?
The 135-degree split point is designed for heavy-duty use in steel and the black oxide finish helps retain hardness during extended drilling sessions.
Does the bit generate excessive heat or vibration during continuous drilling?
The high-speed steel body with black oxide coating reduces friction and heat buildup, while the split point geometry minimises walking and vibration in 31/64 in holes.
What shank size does my drill chuck need to accept this bit?
This jobber-length bit has a straight shank sized to fit standard 1/2 in drill chucks that accommodate the 0.4844 in decimal equivalent diameter.
