Irwin 87950 Speedbor Wood Boring Bit Set 3 Piece

Product Description

The IRWIN INDUSTRIAL TOOL CO 87950 is a three-piece Speedbor wood boring bit set designed for fast, clean through-hole drilling in wood framing, rough carpentry, and general construction applications. The set includes three spade-style bits in 1/2 inch, 3/4 inch, and 1 inch diameters, each cut to a 4-inch short-length shank. This compact length makes the bits well suited for drilling in tight spaces, wall cavities, and stud bays where a full-length bit would be impractical. Licensed electricians, plumbers, and HVAC technicians routinely use sets like this when running pipe, conduit, or flex duct through wood framing members.

The 87950 set is intended for use in residential and light commercial construction and service work. The short 4-inch length is a practical choice for drilling through single studs or joists where bit length and clearance are a concern. Each bit ships carded for easy storage and job-site organization. The set is sold as an individual unit and is packaged in quantities of six per case for supply house stocking.

Installation Notes

Wood boring bits of this type are typically used by electricians, plumbers, and HVAC installers when penetrating wood framing during rough-in work. Ensure the workpiece is properly secured before drilling. Follow applicable building codes, including NEC and IFGC requirements, regarding minimum edge distances and nail plates when boring through structural framing members. Inspect bits for wear or damage before use and discontinue use if the cutting tip is chipped or bent.
