Tempo Communications 33l-3/8 Spade Drill Bit 3/8 Inch

Product Description

The TEMPO COMMUNICATIONS 33l-3/8 is a spade drill bit designed for boring through wood and wood-composite materials. Sized at 3/8 inch in diameter with a 16-inch overall length, it provides the reach needed for running wire or conduit through wall studs, floor joists, and framing members. Electricians and low-voltage technicians rely on long spade bits like this to drill clean through-holes in tight framing cavities without repositioning. The extended shank keeps the bit on axis through thick assemblies, reducing drift and tearout on exit.

This bit is suited for residential and light commercial installation work where cables, wiring, or tubing must pass through structural framing. It handles hardwood, softwood, plywood, and drywall, making it practical across a range of field conditions. Electricians, data and low-voltage installers, and HVAC technicians drilling refrigerant or control-wire pathways will find the 3/8-inch diameter appropriate for standard wire bundle pass-throughs and single-run penetrations.

Key Features

• 3/8-inch cutting diameter sized for standard wire and cable pass-throughs
• 16-inch overall length provides reach through deep framing assemblies
• Compatible with hardwood, softwood, plywood, and drywall
• Extended shank reduces bit deflection in confined framing bays

Compatibility

Designed for use with standard 3/8-inch or larger chuck corded and cordless drills used in electrical, low-voltage, and HVAC rough-in applications.

Installation Notes

A licensed electrician or low-voltage installer typically uses spade bits of this length during rough-in, before drywall is hung. Secure the workpiece or confirm framing is structurally supported before drilling. Wear appropriate eye protection, as long spade bits can produce aggressive chip ejection at speed. Comply with applicable NEC or local building code requirements regarding hole placement and distance from fasteners when drilling through framing members.
