Cleveland C14806 Screw Machine Drill Bit 4.8 Mm Cobalt

Product Description

The CLEVELAND C14806 is a screw machine length cobalt drill bit designed for high-productivity drilling in demanding shop and field environments. Built to an overall length of 2.44 inches with a 4.8 mm (0.1890 inch) diameter, this bit features a 135-degree split point for fast penetration and reduced walking on entry. The M42 cobalt construction handles heat buildup better than standard high-speed steel, making it suited for hard alloys, stainless, and abrasive materials. Licensed tradespeople and machinists reach for this bit when short-flute rigidity and material hardness are both required in the same tool.

The C14806 fits standard screw machine and production drilling setups where a shortened overall length improves rigidity in tight clearances or high-cycle operations. Primary workpiece materials include alloy steels and aluminum. The straight-cylindrical shank at 0.1890 inch diameter seats directly into standard Jacobs-style chucks and quick-change drill chucks without adapters. This bit is appropriate for benchtop drill presses, CNC machining centers, and portable right-angle drills used by HVAC, mechanical, and industrial maintenance technicians.

Key Features

• M42 cobalt steel construction resists heat and wear during extended cuts in hard alloys
• 135-degree split point reduces thrust and prevents center walking on entry
• Web-thinned parallel web improves chip evacuation and cutting efficiency
• Screw machine length (2.44 inches OAL) provides added rigidity over jobber-length bits
• Right-hand cut with regular spiral flutes for standard drilling applications
• Meets ASME B94.11M and DIN 1897 dimensional standards

Compatibility

Designed as an OEM-style replacement or direct-use drill bit for any application requiring a 4.8 mm straight-shank screw machine length bit; compatible with standard drill chucks accepting a 0.1890 inch shank diameter.

Installation Notes

A licensed machinist or trained maintenance technician should confirm workpiece material and cutting speed before use. Secure the workpiece fully before drilling and confirm chuck engagement on the straight-cylindrical shank. Coolant through is not supported on this bit, so apply cutting fluid externally when drilling ferrous alloys to manage heat. Follow applicable shop safety standards and machine guarding requirements during operation.
