Freud DSP1070 Spade Bit 1-1/8 X 4 Inches 5 Pack

Product Description

The FREUD DSP1070 is a 1-1/8-inch by 4-inch Speed Demon spade bit designed for fast, clean hole drilling in wood. The speed-tip geometry self-feeds into the workpiece, reducing the force required to drive the bit and increasing throughput compared to standard flat spade bits. A curved paddle profile accelerates chip evacuation, which keeps the cutting edge clear and allows more holes per battery charge when used with cordless tools. The shank is impact-rated for use in both corded drills and cordless impact drivers, providing added stability and durability under high-torque conditions. Sold in a 5-pack.

This spade bit is suited for residential and light commercial rough-in work where large-diameter holes are bored through wood framing, joists, and studs. Typical applications include running conduit, plumbing pipe, and low-voltage cabling through structural lumber. The 4-inch overall length provides adequate reach for single-stud penetrations, and the self-feeding tip reduces operator fatigue on repetitive drilling tasks. The impact-strong shank makes it a reliable choice for electricians, plumbers, and HVAC installers using modern cordless impact drivers on the job site.

Compatibility

Designed for use in wood and wood-based materials with standard hex-shank drills and impact drivers that accept spade bit shanks.

Installation Notes

Installation is performed by electricians, plumbers, and HVAC technicians during rough-in framing stages. Ensure the drill or impact driver is set to an appropriate speed and torque setting for the material being bored. When drilling near structural members, follow applicable building codes regarding minimum edge distances for notches and holes in framing lumber. Eye protection and secure workpiece clamping are standard practice when using spade bits at high RPM.
