Cleveland C14287 Drill Bit Letter G Cobalt 135 Point

Product Description

The CLEVELAND C14287 is a screw machine length drill bit designed for high-production drilling in demanding trade and industrial applications. Built from M42 cobalt high-speed steel with an oxide straw coating, this bit handles tough materials including stainless steel, nickel alloys, tool steel, cast iron, carbon steel, aluminum, brass, and plastics. The 135-degree split point provides fast penetration with reduced walking, and the parabolic flute geometry promotes efficient chip evacuation. At 2-5/8 inches overall length, the screw machine format keeps the bit rigid and close to the spindle for maximum stability in short-hole drilling operations.

The C14287 is suited for use in drill presses, CNC machining centers, turret lathes, and screw machines where short overall length and straight-cylindrical shanks are required. Its heavy-duty grade and multi-material compatibility make it a practical choice for machinists, maintenance mechanics, and fabrication shops drilling through ferrous and non-ferrous workpieces. The web-thinned parallel web configuration reduces thrust requirements and extends tool life in repetitive production runs.

Key Features

• M42 cobalt steel construction for heat and wear resistance in hard and abrasive materials
• 135-degree split point reduces walking and lowers entry thrust force
• Parabolic flute geometry improves chip flow and reduces clogging in deep or interrupted cuts
• Oxide straw coating provides light lubricity and corrosion resistance
• Web-thinned parallel web decreases cutting resistance and extends tool life
• Screw machine length body maximizes rigidity and minimizes deflection in close-tolerance drilling

Compatibility

Designed for use in screw machines, turret lathes, drill presses, and CNC machining centers accepting a straight-cylindrical shank. Compatible with workpiece materials including aluminum, brass, carbon steel, cast iron, nickel alloy, plastics, stainless steel, and tool steel per Series 2175 specifications.

Installation Notes

Installation is performed by machinists or maintenance mechanics in machine shop or fabrication environments. Secure the straight-cylindrical shank firmly in the chuck or collet before operation and verify runout before engaging the workpiece. Coolant-through capability is not supported on this bit, so external coolant or cutting fluid should be applied as required by the workpiece material. Follow applicable shop safety procedures and ANSI standards for drill press and machine tool operation.
