Cleveland C14533 Screw Machine Drill Bit Wire 48 Cobalt

Product Description

The CLEVELAND C14533 is a cobalt screw machine length drill bit designed for high-performance drilling in demanding shop and field environments. Built to wire size 48, it measures 0.0760 inches in diameter with an overall length of 1-11/16 inches and a flute length of 11/16 inches. The 135-degree split point reduces walking and allows drilling to start without a center punch. Manufactured from M42 cobalt steel, this bit handles heat-resistant alloys and hard materials where high-speed steel tooling falls short. It is sold individually with a minimum order quantity of 10 units.

This bit is suited for screw machine operations, CNC drilling, and manual drill press work in production environments. The short screw machine length increases rigidity and reduces deflection in tight-clearance setups. Primary workpiece materials include alloy steels and aluminum. The straight cylindrical shank fits standard drill chucks without modification, making it a practical choice for machinists, tool and die technicians, and maintenance mechanics working with close-tolerance hole requirements.

Key Features

• Wire size 48 diameter of 0.0760 inches with a tolerance of +0.0000 to -0.0005 inches for consistent hole quality
• 135-degree split point reduces thrust and eliminates the need for center punching on most materials
• M42 cobalt construction provides heat resistance and extended tool life in alloy and hard-material drilling
• Screw machine length body increases rigidity and minimizes deflection compared to jobber-length bits
• Web-thinned parallel web reduces cutting resistance and improves chip evacuation
• Meets ASME B94.11M and DIN 1897 standards for dimensional accuracy and performance

Compatibility

Designed as a replacement or production-use screw machine drill bit for applications requiring wire size 48 diameter drilling in alloy steels and aluminum. Compatible with any standard drill chuck or collet system accepting a 0.0760-inch straight cylindrical shank.

Installation Notes

This bit is installed and operated by machinists or maintenance technicians using standard drill press, CNC machining center, or hand drill equipment. Secure the shank fully in the chuck before operation and verify runout is within acceptable limits for close-tolerance work. Use appropriate cutting fluid for alloy steel applications to extend tool life and maintain surface finish. Never exceed the recommended speed and feed parameters for the workpiece material and bit diameter.
