Eagle Cutting Tool TAC40-021-I Hss Jobber Drill 21/64

Product Description

The EAGLE CUTTING TOOL TAC40-021-I is a 21/64-inch high-speed steel (HSS) jobber-length drill bit designed for general-purpose drilling in metal, wood, and plastic. Jobber-length bits offer a balanced combination of reach and rigidity, making them a reliable choice for production drilling and maintenance work. The HSS construction provides heat resistance and edge retention under moderate cutting speeds. This bit is suited for use in standard drill presses, hand drills, and CNC drilling applications where a mid-range bore diameter is required.

This drill bit is appropriate for residential and light commercial maintenance, fabrication shops, and field service work. It handles common boring tasks in ferrous and non-ferrous metals, hardwoods, and thermoplastics. Electricians, plumbers, HVAC technicians, and general contractors routinely rely on jobber-length HSS bits for structural and equipment-mounting hole applications on the job site.

Key Features

• 21/64-inch diameter for mid-range bore applications
• High-speed steel construction for heat and wear resistance
• Jobber-length geometry balances reach with torsional rigidity
• Compatible with standard drill chucks on hand drills and drill presses
• Suitable for metal, wood, and plastic substrates

Compatibility

Designed as a general-purpose jobber-length drill bit suitable for use in any standard drill chuck accepting a 21/64-inch shank diameter.

Installation Notes

Installation should be performed by a qualified tradesperson familiar with rotary cutting tools and appropriate workholding practices. Secure the workpiece firmly before drilling and verify chuck engagement before applying power. Use appropriate cutting fluid when drilling ferrous metals to extend bit life and reduce heat buildup. Follow all applicable shop-safety and PPE requirements when operating drilling equipment.
