Eagle Cutting Tool SC400-012-I Cobalt Stub Drill 3/16 in

Product Description

The EAGLE CUTTING TOOL SC400-012-I is a 3/16-inch cobalt stub drill designed for professional drilling applications in metal, hardened steel, and other tough materials. Stub drills feature a shorter flute length than standard jobber drills, which reduces deflection and improves rigidity during drilling — a practical advantage when working in tight spaces or drilling through hard stock. Cobalt construction provides enhanced heat resistance and cutting performance compared to standard high-speed steel bits. This bit is suited for use by machinists, pipefitters, electricians, HVAC technicians, and other tradespeople who require precise, controlled hole-making in demanding field or shop conditions.

The SC400-012-I is appropriate for general-purpose drilling in ferrous metals, stainless steel, cast iron, and other hard materials where a standard HSS bit would wear prematurely. The stub-length design makes it well suited for use with drill presses, hand drills, and right-angle drills in confined areas. It is a common choice for tradespeople who need a durable, accurate 3/16-inch hole in structural or mechanical components.

Key Features

• 3/16-inch diameter cobalt stub drill for hard-material applications
• Shorter flute length reduces deflection and improves hole accuracy
• Cobalt construction resists heat buildup at high cutting speeds
• Compatible with standard drill chucks and right-angle drill attachments
• Minimum order quantity of 1 — available as a single unit

Compatibility

Designed as an OEM-style replacement or standard shop consumable for use in any 3/8-inch or larger drill chuck accepting 3/16-inch shank diameter bits.

Installation Notes

This drill bit should be installed and operated by qualified tradespeople familiar with proper drilling technique and machine safety. Always secure the workpiece before drilling, and use appropriate cutting fluid when drilling through hardened or stainless steel to extend bit life. Inspect the bit for wear or chipping before each use and replace when cutting performance degrades. Follow applicable shop safety standards and personal protective equipment requirements when operating drilling equipment.
