Robert Bosch Tool Group DSBS1017 Spade Bit 1-1/4 in 5pk

Product Description

The ROBERT BOSCH TOOL GROUP DSBS1017 is a 1-1/4 inch spade bit engineered for fast, clean boring in wood framing, rough-in work, and general construction applications. This 5-pack ships as individual bits, each featuring a full cone threaded tip that pulls the bit into the material for effortless drilling without excessive downward pressure. A contoured paddle design accelerates chip removal and keeps the bit cutting efficiently through each pass. Electricians, plumbers, and HVAC installers running conduit, pipe, or ductwork through framed walls and floor joists rely on spade bits like this one for high-volume hole boring in production environments.

The DSBS1017 is suited for residential and light commercial rough-in work where consistent hole quality and speed matter. The spur and reamer tips score the perimeter of the hole before the paddle clears material, reducing tear-out and breakout on the exit side. The hex shank power groove locks into standard drill chucks and quick-change chuck systems, reducing bit slippage under torque. This bit is commonly used by electricians pulling wire through studs, plumbers routing supply and drain lines, and HVAC techs running low-voltage control wiring or refrigerant line sets through framing.

Installation Notes

Spade bits are installed by licensed electricians, plumbers, and HVAC technicians as part of rough-in boring tasks and should be used with a variable-speed drill set to an appropriate speed for the material. Always confirm the boring path is clear of energized wiring, gas lines, and structural members before drilling. Wear safety glasses and secure the workpiece before starting the drill. Follow applicable NEC, IPC, or IFGC clearance requirements when boring near structural elements or utility lines.
