Eagle Cutting Tool S304-122-I Cobalt Jobber Drill 22

Product Description

The EAGLE CUTTING TOOL S304-122-I is a Number 22 cobalt jobber-length drill bit designed for general-purpose drilling in metal, stainless steel, cast iron, and other hard materials. Cobalt construction provides superior heat resistance compared to standard high-speed steel, making this bit well-suited for tough, abrasive, or work-hardening materials. The jobber-length body offers a balance of reach and rigidity that covers the majority of through-hole and clearance-hole drilling applications encountered in field and shop environments. Tradespeople and machinists reaching for a reliable Number 22 drill bit will find this a direct fit for standard jobber-length tasks.

This bit is appropriate for use in residential, commercial, and light industrial settings wherever a Number 22 wire-gauge hole size is required. Common applications include pilot holes, tapping prep, electrical conduit work, plumbing rough-in, HVAC bracket fabrication, and sheet-metal work. The cobalt construction makes it a preferred choice when drilling into stainless fasteners, hard alloys, or materials that quickly dull standard HSS tooling. It is compatible with standard drill chucks found on corded or cordless drill drivers, drill presses, and magnetic base drills.

Key Features

• Cobalt construction for enhanced heat resistance and extended tool life in hard materials
• Number 22 wire-gauge diameter for precise clearance and tapping applications
• Jobber length provides versatile reach-to-rigidity ratio for general drilling tasks
• Compatible with standard drill chucks on portable and stationary equipment
• Minimum order quantity of 1 allows single-unit procurement

Compatibility

Designed as a standard jobber-length replacement or stock bit for use wherever a Number 22 diameter cobalt drill is specified. Fits any drill chuck accepting standard jobber-length shanks.

Installation Notes

Installation is performed by qualified machinists, HVAC technicians, electricians, plumbers, or other tradespeople with experience operating drilling equipment. Secure the workpiece firmly before drilling and use appropriate cutting fluid or lubricant when drilling ferrous metals to extend bit life and reduce heat buildup. Inspect the cutting edges before each use and replace the bit if chipping or excessive wear is present. Follow applicable shop-safety and PPE requirements when operating rotary cutting tools.
