Jobber Length Drill Bit 11/64
This jobber length drill bit measures 11/64 inch and is built from high speed steel for general purpose drilling. It suits machinists and maintenance technicians who need a reliable fractional size bit for everyday workshop tasks. The split point tip helps reduce walking on contact. The decimal equivalent is .1719 inch.
High Speed Steel Black Oxide Finish
The black oxide coating adds corrosion resistance and helps retain lubricant during use. High speed steel construction provides hardness and heat resistance for drilling in steel, cast iron and other ferrous materials. The 135 degree point angle supports faster penetration and reduced thrust. The bit fits standard three jaw chucks without adapters.
Split Point Geometry for Controlled Drilling
The split point design centres the bit quickly and lowers the force required to start a hole. This reduces heat buildup and extends edge life in normal hand held or drill press applications. The jobber length offers a balanced reach for typical material thicknesses. California Proposition 65 warnings apply to this product.

Questions about this item
What materials can the 135 degree split point on this 11/64 inch HSS drill bit effectively start in?
The 135 degree split point is designed for efficient starting in harder materials such as stainless steel and alloy steels, reducing walking and the need for centre punching.
What chuck capacity is required to hold the 11/64 inch shank of this jobber length drill bit?
A drill chuck with a minimum capacity of 11/64 inch (0.1719 inch decimal equivalent) is needed to secure the straight shank of this bit.
Does the black oxide finish on this high speed steel bit require a specific break-in procedure before first use?
No special break-in is required; the black oxide finish provides corrosion resistance and helps retain cutting fluid during normal drilling operations from the first hole.
