Eagle Cutting Tool SC400-016-D Cobalt Stub Drill 1/4 in

Product Description

The EAGLE CUTTING TOOL SC400-016-D is a 1/4-inch cobalt stub drill designed for high-speed drilling in hard and abrasive materials. The 135-degree split point geometry reduces walking on entry and requires less feed pressure compared to conventional 118-degree points. The stub-length body provides added rigidity over a standard jobber drill, making it well suited for applications where bit deflection or breakage is a concern. This drill is manufactured in the USA and is intended for use by machinists, pipefitters, electricians, plumbers, and HVAC technicians who drill into hardened steel, stainless, cast iron, and similar tough materials.

The SC400-016-D is used in residential and commercial trade work where a short, stiff drill is preferred over a longer jobber-length bit. Typical applications include drilling through structural steel, pipe hangers, electrical enclosures, and equipment frames. The cobalt composition provides heat resistance that allows the bit to maintain its edge under sustained drilling loads without the need for frequent resharpening. It is a direct-use replacement for standard 1/4-inch stub drills on the jobsite or in a machine shop environment.

Key Features

• Cobalt high-speed steel construction resists heat buildup during prolonged drilling in hard metals
• 135-degree split point reduces center walking and lowers required feed force on entry
• Stub-length body increases rigidity and reduces deflection compared to jobber-length drills
• 1/4-inch diameter suits common pilot and through-hole requirements across trade applications
• Manufactured in the USA

Compatibility

Designed as a standard 1/4-inch stub-length drill suitable for use in any drill press, hand drill, or milling machine chuck that accepts a 1/4-inch straight shank bit.

Installation Notes

Secure the bit firmly in the chuck before operation and verify the shank is fully seated. Use cutting fluid or oil when drilling through stainless steel or hardened alloys to extend bit life and manage heat. Reduce feed pressure as the drill breaks through the material to prevent grabbing. This type of tooling should be handled and replaced by qualified tradespeople following applicable shop safety and OSHA general industry standards.
