Cle-line C20516 9/64 Inch Mechanics Drill Bit Hss Hex Shank

Product Description

The CLE-LINE C20516 is a mechanics-length drill bit designed for general-purpose drilling in steel and similar materials. It features a 9/64 inch diameter cutting edge ground to a 118-degree split point, which self-centers on contact and reduces the walking common with standard point geometry. The high-speed steel construction handles the heat and stress of production drilling without premature edge failure. A 1/4 inch hex shank seats directly into impact drivers and quick-change chuck systems, making tool swaps fast on the job. Overall length is 3.785 inches, keeping the bit compact and rigid in tight work envelopes.

This bit is suited for sheet metal fabrication, mechanical assembly, and maintenance work where a short, stiff drill is preferred over jobber-length alternatives. The mechanics-length body reduces deflection when starting holes in hard stock or when drilling at slight angles. It is a right-hand cut, spiral-flute design compatible with standard drill presses, cordless drivers, and corded drills equipped with a 1/4 inch hex chuck or adapter. Tradespeople in HVAC, electrical, and general mechanical service will find this format practical for drilling pilot holes in enclosures, brackets, and structural steel.

Key Features

• 9/64 inch diameter with 0.1406 inch decimal equivalent for precise sizing
• 118-degree split point self-centers and reduces drill walking on hard surfaces
• High-speed steel construction resists heat buildup during steel drilling
• 1/4 inch hex shank fits impact drivers and quick-change systems without an adapter
• Mechanics length at 3.785 inches overall provides added rigidity over jobber-length bits
• Bright uncoated finish allows easy visual inspection of cutting edge condition

Compatibility

Designed for use with 1/4 inch hex chuck cordless drivers, impact drivers, and drill presses fitted with a 1/4 inch hex adapter. Primary workpiece material is steel; general-purpose performance across comparable ferrous stock.

Installation Notes

Install the hex shank fully into the chuck or quick-change holder before drilling to prevent slippage under load. Secure the workpiece before starting the cut and apply steady, consistent feed pressure to avoid bit deflection or breakage. Disconnect or power down the drill before changing bits. Licensed tradespeople should follow applicable workplace safety codes when drilling into structural or electrical enclosure materials.
