17/64-inch Split-Point Drill Bit

The Cle-Line C23138 is a jobber-length drill bit sized at 17/64 inch with a 135-degree split point. It targets metalworkers and maintenance technicians who need accurate hole starts in steel and other ferrous materials. The fractional sizing suits imperial-specification projects and general workshop use.

High-Speed Steel with Black Oxide

High-speed steel construction provides the hardness and heat resistance required for repetitive drilling cycles. Black oxide finish adds lubricity and helps resist chip welding during extended cuts. The straight shank fits standard three-jaw chucks without adapters, so changeover is quick on any drill press or handheld motor.

135-Degree Split Point Geometry

The 135-degree split point is the specification that determines suitability: it reduces thrust force and prevents walking on hard surfaces, making this bit the right choice for stainless and alloy steels. Buyers drilling softer materials such as wood or plastic will not benefit from the aggressive angle and should select a different point style.

Questions about this item

What does the 135-degree split point do for drilling?

The 135-degree split point reduces walking and starts the cut faster on metal, wood and plastic without a centre punch.

What shank size fits a standard 17/64-inch jobber bit?

The shank matches the 17/64-inch drill diameter, so it fits any three-jaw chuck that accepts 0.2656-inch round shanks.

How do I keep the black-oxide finish from wearing off too quickly?

Use cutting fluid, run the correct RPM for the material and ease pressure at breakthrough to protect the black-oxide coating.
