Robert Bosch Tool Group DSB1021 Spade Bit 1-1/2x6

Product Description

The ROBERT BOSCH TOOL GROUP DSB1021 is a 1-1/2 inch by 6 inch spade bit from the Daredevil line, engineered for fast, clean boring through wood framing, studs, and dimensional lumber. The full cone threaded tip pulls the bit into the material without requiring heavy downward pressure, reducing operator fatigue on repetitive drilling tasks. A contoured paddle accelerates chip evacuation, keeping the flutes clear and reducing heat buildup at speed. Spur and reamer tips score the perimeter of the hole before the paddle clears material, producing a cleaner entry and exit. The 1/4 inch hex shank fits standard quick-change chucks. Package quantity is 5 bits.

This bit is suited for residential and light commercial rough-in work where electricians, plumbers, and HVAC technicians need to bore through wood framing for cable, conduit, or pipe runs. The 6 inch overall length and 5 inch drilling depth allow it to clear typical stud and joist material in a single pass without an extension. The 1-1/2 inch diameter is a common size for low-voltage cabling and small-diameter pipe rough-in penetrations.

Installation Notes

Electricians, plumbers, and HVAC technicians are the primary installers for this bit type during rough-in framing stages. Ensure the drill is set to an appropriate speed for the wood species being bored — lower speeds generally suit harder materials. Verify that the boring location is clear of existing fasteners, wiring, and mechanical lines before drilling. Follow NEC, IPC, and IFGC clearance requirements when boring through structural members for utility penetrations.
