Cle-Line C23136 Jobber Drill Bit

The Cle-Line C23136 is a fractional-inch jobber length drill bit sized at 15/64 in. It is designed for general-purpose drilling in metal, wood, and plastic using standard portable drills or drill presses. The high-speed steel construction with black oxide finish provides durability for workshop and maintenance tasks.

Installation and Common Issues

The bit fits any chuck that accepts a 15/64 in shank and requires no special tools or adapters for installation. The 135-degree split point is self-centering to reduce walking on hard surfaces and helps the bit start cleanly without a centre punch. Overheating can dull the cutting edges quickly since the bit has no coolant holes, so use cutting fluid and moderate pressure.

135-Degree Split Point Geometry

The 135-degree split point angle is the critical specification that determines suitability for harder materials such as stainless steel or hardened alloys. Buyers drilling only soft wood or plastic may not need this aggressive geometry. The decimal equivalent of .2344 in confirms the exact hole size produced for precision fitting applications.

Questions about this item

How can I verify the 135 degree split point is cutting correctly after first use?

The bit should start on contact without walking and produce short, curled chips in steel; the 135 degree split point is designed for self-centering in hard materials.

What comes in the package and is a drill chuck included?

The box contains the single 15/64 inch jobber length drill bit; a compatible drill chuck or collet must be supplied separately.

When should I choose the 15/64 inch size over another fractional diameter?

Select this 15/64 inch bit when the hole diameter must equal 0.2344 inch decimal equivalent for fastener clearance or tap drill requirements.
