Eagle Cutting Tool T500-021-I 21/64 Jobber Drill Bit

Product Description

The EAGLE CUTTING TOOL T500-021-I is a 21/64 inch HSS (high-speed steel) jobber-length drill bit with a titanium nitride (TiN) coating. The TiN coating increases surface hardness and reduces friction, extending cutting life compared to uncoated HSS tooling. This drill bit is suited for general-purpose drilling in metal, wood, plastic, and composite materials. It is commonly stocked by electricians, plumbers, HVAC technicians, and maintenance trades for field drilling tasks on structural members, enclosures, and mechanical components.

The T500-021-I is appropriate for use in standard drill presses, cordless drills, and hand-held electric drills across residential and light commercial applications. The jobber-length flute geometry provides a balance of reach and rigidity suited to most common drilling scenarios encountered in trade work. This is an import-grade bit intended for general service use rather than precision machining environments.

Key Features

Compatibility

Designed as a general-purpose jobber drill bit for use in standard drill presses and portable electric drills equipped with 3/8 inch or 1/2 inch chucks across trade and maintenance applications.

Installation Notes

Installation of this drill bit is performed by electricians, HVAC technicians, plumbers, and general maintenance trades. Secure the bit fully in the chuck and verify it runs true before drilling. Always wear appropriate eye protection when drilling metal or composite materials. Reduce feed pressure as the bit breaks through the workpiece to prevent grabbing or deflection.
