Cleveland C14603 Cobalt Screw Machine Drill Bit Wire 16

Product Description

The CLEVELAND C14603 is a cobalt screw machine length drill bit designed for high-performance drilling in demanding trade and production environments. Built from M42 cobalt tool steel with a coated finish, it offers increased heat and wear resistance compared to standard high-speed steel bits. The bit carries a wire size 16 designation with a decimal diameter of 0.1770 inches and an overall length of 2-3/16 inches. The 135-degree split point reduces walking on contact and allows drilling to begin without a center punch in most applications. Right-hand cut geometry and a regular spiral flute pattern support efficient chip evacuation.

This bit is suited for drilling alloy steel and aluminum in screw machine, production, and maintenance shop applications. Its screw machine length profile — shorter than a jobber bit — provides added rigidity in tight clearance setups and chuck-heavy operations. The straight cylindrical shank seats directly in standard drill chucks without adapters. Machinists, tool room technicians, and industrial maintenance professionals working in metal fabrication and production drilling applications will find this bit appropriate for repetitive, close-tolerance work.

Key Features

• M42 cobalt tool steel construction for elevated heat resistance in tough materials
• 135-degree split point reduces thrust and eliminates the need for center-punching on most surfaces
• Web-thinned, parallel web configuration promotes chip clearance and reduces cutting resistance
• Screw machine length body adds rigidity over jobber-length bits in confined setups
• Diameter tolerance held to +0.0000 to -0.0007 inches for consistent fit in close-tolerance holes
• Conforms to ASME B94.11M and DIN 1897 standards

Compatibility

Designed as an OEM-style replacement or direct addition for production and maintenance drilling setups requiring a wire size 16 screw machine length bit in cobalt tool steel. Compatible with any standard drill chuck accepting a 0.1770-inch straight cylindrical shank.

Installation Notes

Installation is performed by machinists, tool room technicians, or maintenance mechanics using standard keyed or keyless drill chucks on drill presses, CNC machining centers, or hand drills. Ensure the shank is fully seated and the chuck is tightened securely before operation. Follow facility lockout/tagout procedures before changing bits on powered equipment. Do not exceed the recommended cutting speed for the workpiece material, and use appropriate cutting fluid when drilling alloy steel to extend tool life.
