Cleveland C15295 Cobalt Screw Machine Drill Bit No. 5

Product Description

The CLEVELAND C15295 is a cobalt screw machine length drill bit designed for demanding metal-cutting applications in industrial and shop environments. Built to ASME B94.11M standards, it carries a wire gauge size of No. 5 (0.2055 inches decimal) with a 135-degree split point and a parabolic flute geometry that promotes fast chip evacuation and reduced thrust. The two-flute, web-thinned design paired with a straight-cylindrical shank makes this bit well suited for production drilling operations where shorter overall length improves rigidity and accuracy. Machinists, tool-and-die technicians, and maintenance mechanics rely on this style of bit for high-cycle work in alloy steels and aluminum.

The C15295 is intended for screw machine, CNC, and drill press applications where stub-length rigidity is preferred over jobber-length reach. Its M42 cobalt material grade resists heat buildup during continuous cutting in alloy steels, stainless steels, and aluminum stock. The parallel web configuration and split point geometry reduce walking on entry, making it a practical choice for close-tolerance work in production and job-shop settings where hole location and diameter consistency are critical.

Key Features

• No. 5 wire size, 0.2055 inch decimal diameter with a tolerance of +0.0000 to -0.0007 inches
• M42 cobalt material grade for elevated heat resistance in tough alloy and non-ferrous materials
• 135-degree split point reduces thrust and eliminates center-punch requirement on most setups
• Parabolic flute profile promotes rapid chip clearing and reduces re-cutting in deep holes
• Web-thinned, parallel web construction lowers cutting resistance and extends tool life
• Right-hand cut with straight-cylindrical shank compatible with standard drill chucks and collets
• Meets ASME B94.11M and ANSI specification designation

Compatibility

Designed as an OEM-style screw machine length drill bit suitable for use in standard drill chucks, collets, and toolholders accepting a 0.2055-inch straight-cylindrical shank across CNC machining centers, turret screw machines, and bench-top drill presses.

Installation Notes

Secure the shank fully into the chuck or collet before operation and verify runout with a dial indicator for close-tolerance work. Power down and lock out the machine spindle before changing or inspecting bits. Use appropriate cutting fluid or coolant compatible with cobalt tooling when drilling alloy steels to extend tool life, noting that this bit does not support internal coolant-through delivery. Follow shop safety protocols and applicable OSHA machine-guarding requirements during setup and use.
