Irwin 88716 Speedbor Wood Spade Bit 1x16 Inch 6 Pack

Product Description

The IRWIN INDUSTRIAL TOOL CO 88716 is a Speedbor wood spade bit designed for boring clean, fast holes through dimensional lumber, engineered wood, and similar materials. Measuring 1 inch in diameter and 16 inches in length, this extended-reach bit handles deep drilling applications where a standard-length spade bit falls short. The package includes 6 bits, making it a practical stock item for trade professionals who burn through tooling on large framing, rough-in, or mechanical installation projects. Electricians, plumbers, and HVAC techs running conduit, pipe, or ductwork through wood framing are the primary users of a bit in this configuration.

The 88716 is suited for residential and light commercial rough-in work where trade professionals need to bore through multiple studs or joists in a single pass. The 16-inch length provides the reach needed to drill through double or triple framing members without repositioning. It is a standard tool for drilling wire, pipe, and duct penetrations through wood-framed walls, floors, and ceilings. The 6-unit pack supports job-site crews or service vehicles that need redundant tooling on hand.

Key Features

• 1-inch diameter for standard rough-in hole sizing through wood framing
• 16-inch length provides extended reach for deep or multi-member drilling
• Spade bit geometry optimized for fast material removal in wood
• Packaged in a quantity of 6 for crew-level or fleet stocking
• Compatible with standard hex-shank and keyed drill chucks

Compatibility

Designed as a standard spade bit replacement for use with corded or cordless drills equipped to accept a spade bit shank, typical in residential and light commercial wood-framing applications.

Installation Notes

Spade bits of this type are installed and used by electricians, plumbers, and HVAC technicians performing rough-in drilling through wood-framed assemblies. Ensure the drill is set to an appropriate speed for the material and bit diameter before starting. Inspect the bit tip and cutting edges before each use and retire any bit showing significant wear or damage. Follow applicable NEC, IPC, or IFGC clearance requirements when locating penetrations through structural framing members.
