Irwin Industrial Tool Co 87954 Spade Bit Set 4 Piece

Product Description

The IRWIN INDUSTRIAL TOOL CO 87954 is a 4-piece spade bit set designed for wood boring applications. Each bit measures 4 inches in length, making this set well suited for drilling in tight spaces where a standard-length bit would not fit. The set features a patented Blue Groove point and cutting edge for faster chip removal, double cutting spurs that scribe the outside of the hole to reduce breakout, and a thicker cutting edge for extended drilling life. The quick-change shank fits all standard 1/4-inch quick-change chucks for fast bit swaps on the job. Carpenters, electricians, plumbers, and general contractors commonly keep this set on hand for rough-in and finish drilling work in wood framing and structural members.

This set is intended for use in residential and light commercial construction and renovation. The compact 4-inch bit length is especially useful when working inside wall cavities, floor joists, and other confined framing bays. The quick-change shank eliminates the need for a chuck key and speeds up transitions between bit sizes. The set includes one each of the following Speedbor bits: 5/8 inch, 3/4 inch, 1 inch, and 1-1/2 inch.

Installation Notes

Spade bits of this type are installed by trade professionals including electricians and plumbers for boring through wood framing during rough-in work. Confirm the drill or driver is powered off and the chuck is disengaged before changing bits. Use appropriate eye protection and secure the workpiece before drilling. Follow applicable codes such as NEC or IPC when drilling through structural members to maintain required edge and nail-plate distances.
