Eagle Cutting Tool SC400-027-I Cobalt Stub Drill 27/64

Product Description

The EAGLE CUTTING TOOL SC400-027-I is a 27/64-inch cobalt stub drill designed for drilling into hard and abrasion-resistant materials. Stub-length drills feature a shorter flute and overall length compared to jobber-length bits, providing increased rigidity and reduced deflection in applications where hole accuracy is critical. The cobalt construction improves heat resistance, making this bit suitable for use in high-speed drilling operations through tough metals. It is a common tool in the inventory of electricians, HVAC technicians, plumbers, and other trade professionals who need reliable performance when drilling through steel, stainless steel, cast iron, and similar hard stock.

This stub drill is well suited for trade and light industrial applications where a standard jobber-length bit would flex or chatter. The shorter body improves control when drilling in tight or confined spaces, such as equipment enclosures, panel boxes, and mechanical rooms. The 27/64-inch diameter is frequently used when drilling pilot or clearance holes for fasteners and fittings in metal fabrication and field service work.

Key Features

• Cobalt construction provides superior heat resistance for drilling hard metals
• Stub length reduces deflection and improves hole accuracy versus jobber-length bits
• 27/64-inch diameter suits common fastener and fitting clearance applications
• Rigid geometry allows use in confined or restricted-access drilling locations
• Compatible with standard drill chucks used in corded and cordless tools

Compatibility

Designed as an OEM-style replacement or stock bit for trade professionals requiring a 27/64-inch cobalt stub-length drill for use in standard three-jaw drill chucks on corded or cordless drill drivers and drill presses.

Installation Notes

This drill bit is installed and removed by a licensed or qualified trade professional using a standard keyed or keyless drill chuck. Always secure the workpiece before drilling and use appropriate cutting fluid when drilling stainless steel or hardened metals to extend bit life. Wear proper eye protection per applicable safety standards. Inspect the cutting edges before each use and replace any bit that shows signs of chipping or excessive wear.
