Cleveland C16567 Drill Bit Letter E 1/4 in 135 Cobalt

Product Description

The CLEVELAND C16567 is a jobber-length twist drill bit designed for heavy-duty metal drilling applications. Built from M42 cobalt high-speed steel with a gold oxide coating, this bit delivers extended tool life when cutting hard and abrasive materials. The 135-degree split point starts on contact without center-punching and reduces thrust. A parabolic flute geometry clears chips efficiently, reducing heat buildup during deep drilling. The straight-cylindrical shank measures 1/4 inch in diameter, compatible with standard drill chucks and quick-change systems. This is a right-hand-cut bit with a web-thinned, tapered web for improved cutting performance in production and maintenance environments.

The C16567 is suited for drilling cast iron, stainless steel, carbon steel, and non-ferrous metals in fabrication shops, maintenance facilities, and field service settings. The cobalt M42 material grade makes it a reliable choice when carbon steel bits fail prematurely due to work hardening or elevated cutting temperatures. The 4-inch overall length and 2-3/4-inch flute length accommodate typical stock thicknesses encountered in structural and sheet metal work.

Key Features

• M42 cobalt steel construction for extended life in hard and abrasive materials
• 135-degree split point for no-skate starts and reduced feed pressure
• Parabolic flute profile for fast chip evacuation and reduced heat
• Gold oxide finish reduces friction at the cutting edge
• Web-thinned tapered web improves cutting efficiency
• Meets ASME B94.11M and DIN 338 standards

Compatibility

Designed for use in standard 1/4-inch keyed or keyless drill chucks. Suitable for drilling cast iron, non-ferrous metals, stainless steel, and carbon steel workpieces. Part of the CLEVELAND Series 2075 heavy-duty jobber drill line.

Installation Notes

Installation and use should be performed by a qualified machinist or maintenance technician familiar with metal drilling operations. Secure the workpiece firmly before drilling and verify chuck runout before use. Always wear appropriate eye protection and follow applicable shop safety procedures. Do not exceed the recommended feed and speed range for the workpiece material to avoid premature edge wear or bit failure.
