Tempo Communications 33l-3/4 Spade Drill Bit 3/4x16 Inch

Product Description

The TEMPO COMMUNICATIONS 33l-3/4 is a spade drill bit designed for boring through wood substrates in trade installation work. At 3/4 inch in diameter and 16 inches in length, this bit reaches deep into wall cavities, floor joists, and structural members where standard-length bits cannot access. Electricians, low-voltage installers, and plumbers rely on extended spade bits like this one to run conduit, cable, and pipe through framing without requiring offset drilling or multiple access points. The 3/4-inch bore diameter accommodates a common range of cable and conduit pass-through applications.

This bit is suited for residential and light commercial rough-in work where drilling through hardwood, softwood, plywood, and drywall is required. It is a standard tool in the kit of electricians fishing wire through framed walls, low-voltage techs running coax or data cable, and plumbers routing supply or drain lines through wood framing. The 16-inch length is particularly useful for drilling through double-stacked framing members or reaching through deep wall assemblies from a single access point.

Key Features

• 3/4 inch diameter bore suited for cable, conduit, and pipe pass-through applications
• 16-inch length allows drilling through deep wall cavities and stacked framing members
• Compatible with hardwood, softwood, plywood, and drywall substrates
• Extended reach reduces the need for multiple drill points on deep assemblies

Compatibility

Designed for use with standard 3/8-inch or 1/2-inch chuck drill drivers used in electrical, low-voltage, and plumbing rough-in installations.

Installation Notes

This bit is installed and used by electricians, low-voltage technicians, and plumbers during rough-in phases. Always confirm framing is clear of hidden utilities before drilling, and follow NEC or applicable local code requirements for cable and conduit clearance distances from framing edges. Secure the workpiece where possible and use appropriate eye protection when boring overhead or into walls. Allow the bit to clear chips periodically when drilling through thick or laminated materials to prevent binding.
