Cleveland C14515 Screw Machine Drill Bit 54 Cobalt

Product Description

The CLEVELAND C14515 is a cobalt screw machine length drill bit designed for high-performance drilling in demanding shop and field applications. Built to M42 cobalt material grade, this bit delivers heat resistance and edge retention when cutting through tough alloy steels and non-ferrous metals. The 135-degree split point reduces walking at startup and lowers thrust requirements, making it well suited for production drilling and repetitive operations. The web-thinned, parallel web configuration maintains cutting efficiency across the full flute length. At 1.625 inches overall length, this stub-length geometry provides rigidity and reduces deflection in close-tolerance work.

This bit is intended for use in screw machine operations, CNC machining centers, drill presses, and hand drilling applications where stub-length rigidity is required. Its 0.0550-inch diameter targets fine-hole work in alloy steel and aluminum workpieces. The straight cylindrical shank fits standard drill chucks without adapters. It conforms to ASME B94.11M and DIN 1897 standards, making it appropriate for shops operating under ANSI or DIN specification requirements. This is a heavy-duty grade bit intended for professional machinists and metalworking tradespeople.

Key Features

• M42 cobalt construction provides heat resistance and extended tool life in hard alloy materials
• 135-degree split point reduces thrust and prevents walking on entry
• Web-thinned parallel web maintains cutting efficiency and chip evacuation
• Screw machine (stub) length of 1.625 inches overall delivers increased rigidity and reduced deflection
• Right-hand cut with 2-flute regular spiral geometry for consistent chip removal
• Diameter tolerance of +0.0000 to -0.0005 inches supports close-tolerance hole requirements
• Meets ASME B94.11M and DIN 1897 specifications

Compatibility

Designed for drilling alloy steel and aluminum workpieces. Straight cylindrical shank fits standard drill chucks. Conforms to ANSI and DIN specification requirements per Series 2133.

Installation Notes

This bit is installed and operated by professional machinists and metalworking technicians. Secure the straight shank fully in a keyed or keyless drill chuck before operation and verify chuck runout is within acceptable tolerance for the hole size. Use appropriate cutting fluid or coolant for the workpiece material to preserve edge life. Inspect the cutting edges for wear or chipping before each use and replace the bit if the split point geometry is compromised.
