Description

Maximize Drilling Efficiency: Diablo SPEEDemon 2-9/16 Inch Self-Feed Bit

Revolutionize your rough-in work with the Diablo DSF2562 2-9/16 in. SPEEDemon™ Self-Feed Bit. Designed to meet the rigorous demands of professional plumbers and electricians, this bit is engineered using a precision heat-forging process that guarantees strict tolerances and superior durability. The result is a high-performance tool that drills up to 2X faster in softwoods while delivering up to 2X more holes per battery charge compared to standard bits. Whether you are drilling through studs for 2-inch PVC pipe or running large conduit, this bit ensures smooth, effortless operation that preserves your cordless drill's battery life.

The secret to its speed lies in the aggressive low-thread count feed screw, which pulls the bit through the material with minimal effort while preventing pitch build-up. Unlike traditional bits, the SPEEDemon features a 2-cutter head design forged from premium steel for consistent, balanced drilling. It also solves a common jobsite frustration with its unique pull-out stop mechanism, which prevents the feed screw from slipping out or getting lost when withdrawing the bit from deep holes. With a 7/16-inch hex shank, it locks securely into quick-change chucks and right-angle drills for maximum torque transfer.

Key Features

  • Precision Heat Forged: Premium steel construction ensures quality, consistency, and up to 2X longer life.

Pro-Tip: The 2-9/16" diameter is the industry standard size for installing 2-inch PVC pipe (which has an actual outside diameter of roughly 2.375"). This bit leaves just enough clearance for the pipe to slide through easily without being too loose. When drilling multiple studs in a row, use a right-angle drill with an auxiliary handle to manage the high torque safely.
