Tempo Communications 33l-1/2 Spade Drill Bit 1/2 X 16 Inch

Product Description

The TEMPO COMMUNICATIONS 33l-1/2 is a long-reach spade drill bit designed for boring clean holes through wood framing, sheathing, and finish materials. At 1/2 inch in diameter and 16 inches in length, it gives electricians, low-voltage installers, and other trades the reach needed to drill through wall cavities, floor joists, and structural members without extension attachments. The flat spade geometry cuts efficiently through hardwood, softwood, plywood, and drywall, making it practical for rough-in and retrofit work where controlled hole placement matters.

This bit is suited for residential and light commercial installation work where wiring, cable, or pipe needs to be run through wood-framed assemblies. Common applications include pulling wire through stud bays, drilling through top and bottom plates, and creating access holes in plywood subfloor or sheathing. Its 16-inch length is particularly useful in retrofit scenarios where standard-length bits cannot reach the target location without opening walls.

Key Features

• 1/2 inch diameter for standard wire and cable clearance holes
• 16 inch overall length provides extended reach through framing cavities
• Spade bit geometry cuts hardwood, softwood, plywood, and drywall
• Long-reach design reduces need for bit extensions in retrofit installs

Compatibility

Designed for use with standard corded or cordless drills accepting 1/4 inch hex or round shank spade bit drives. Suitable for boring through wood framing materials including hardwood, softwood, plywood, and drywall in typical residential and commercial rough-in applications.

Installation Notes

Electricians and low-voltage technicians should confirm bit shank compatibility with the drill chuck before use. When drilling through structural members, follow applicable building codes regarding allowable hole size and placement relative to the member edge. Wear appropriate eye protection when boring through overhead or vertical surfaces. Remove the bit from the material before setting down a running drill to avoid uncontrolled movement.
