Import -20907-10 Mechanics Drill Bit 11/64 in Hss

Product Description

The IMPORT -20907-10 is a mechanics-length, high speed steel (HSS) drill bit designed for general-purpose drilling in metal and hard materials. The split point tip reduces walking on contact and requires no center punch for most applications. An oxide finish provides basic lubrication and corrosion resistance during operation. The straight-cylindrical shank seats securely in standard three-jaw drill chucks. With an overall length of 2-7/8 inches and a 135-degree drill point angle, this bit is sized for compact access and controlled penetration in production and maintenance drilling tasks. It is installed and used by machinists, millwrights, pipefitters, and general maintenance technicians.

This 11/64 inch diameter drill bit is suited for drilling carbon steel, cast iron, high alloy steel, high tensile strength alloy, stainless steel, and general steel workpieces. The mechanics length — shorter than a jobber bit — improves rigidity and reduces deflection in tight or confined drilling situations. It is commonly used in shop fabrication, field maintenance, and light manufacturing environments where a compact, accurate drill bit is required.

Key Features

• 11/64 inch (0.1719 inch decimal) diameter for precise hole sizing
• 135-degree split point angle reduces bit walking and eliminates the need for a center punch in most setups
• High speed steel construction withstands heat generated during metal drilling
• Oxide finish provides basic lubrication and surface protection
• Mechanics length (2-7/8 inches OAL) improves rigidity and suits confined spaces
• Right-hand spiral flutes, web-thinned with parallel web configuration for efficient chip evacuation

Compatibility

Designed as a general-purpose mechanics-length drill bit compatible with standard three-jaw keyed and keyless drill chucks accepting straight-cylindrical shanks. Suitable for use in benchtop drill presses, hand drills, and drill motors used in metal fabrication and maintenance applications.

Installation Notes

Secure the bit fully in the chuck and verify it is centered and tight before starting the drill. Apply cutting fluid or lubricant when drilling stainless steel, high alloy steel, or high tensile strength materials to extend bit life and improve cut quality. Use appropriate RPM for the workpiece material and bit diameter — higher speeds suit softer metals, lower speeds suit hard alloys. Wear appropriate eye protection and secure the workpiece before drilling.
