Disston Company 571141 Hss Drill Bit 1/8 X 6 Inch

Product Description

The DISSTON COMPANY 571141 is a 1/8-inch diameter by 6-inch extra-length high speed steel drill bit with a black oxide finish. It features a 135-degree split-point tip with four cutting edges that prevent walking on contact and allow fast penetration without a center punch. The black oxide tempering treatment lowers frictional resistance and improves chip evacuation during the cut. At 0.03 pounds, this bit is sized for detail and through-hole work in confined or deep-reach applications where standard-length bits fall short.

This drill bit is suited for residential and light commercial work across multiple substrates. Recommended materials include wood, plastic, wallboard, plywood, soft metals, aluminum, brass, and bronze. It can be used occasionally in stainless steel and other hard metals where a true HSS bit is acceptable for intermittent service. Typical users include electricians, plumbers, HVAC technicians, and general tradespeople who need a longer reach when drilling through framing members, panels, or layered assemblies.

Key Features

• 135-degree split-point tip with four cutting edges eliminates walking and reduces the need for a center punch
• Extra length at 6 inches provides reach for deep-hole and through-framing applications
• High speed steel construction handles a wide range of substrates including soft metals
• Black oxide tempering treatment reduces friction and promotes chip flow
• 1/8-inch diameter suited for pilot holes, wire-routing holes, and small-diameter fastener clearance

Compatibility

Recommended for use in wood, plastic, wallboard, plywood, soft metals, aluminum, brass, and bronze. Suitable for occasional use in stainless steel and other hard metals. Compatible with standard 3-jaw drill chucks that accept 1/8-inch round shanks.

Installation Notes

Install in a keyed or keyless chuck rated for the intended RPM before applying power. For best results in metal, use cutting fluid to manage heat buildup, especially in stainless steel or hard alloys. Disconnect power tools from the power source before changing bits. Follow applicable OSHA and job-site PPE requirements including eye protection when drilling.
