Cleveland C14597 Cobalt Drill Bit Wire 19 0.166 in 135pt

Product Description

The CLEVELAND C14597 is a screw machine length drill bit designed for high-performance drilling in demanding trade and industrial applications. Built from M42 cobalt high-speed steel, it carries a 135-degree split point that self-centers on contact and reduces walking without a center punch. The bit measures 2.125 inches overall length with a 1.0625-inch flute length, making it well suited for drilling in tight clearances where a jobber-length bit would not fit. Two right-hand spiral flutes evacuate chips efficiently during drilling cycles. This is a heavy-duty grade bit conforming to ASME B94.11M and DIN 1897 standards, appropriate for machinists, maintenance technicians, and tool-room professionals who need consistent dimensional accuracy in production or repair work.

The C14597 is intended for drilling alloy steel, aluminum, and similar workpiece materials where heat resistance and edge retention are priorities. Its web-thinned, parallel-web construction reduces thrust load at the cutting tip, which is particularly useful when drilling harder alloys by hand or under power feed. The straight cylindrical shank seats securely in standard drill chucks and CNC tool holders. The screw machine length format is a common choice for drill press work, turret lathes, and other setups where reduced overhang improves rigidity and hole quality.

Key Features

• M42 cobalt construction for elevated heat resistance and extended tool life in hard materials
• 135-degree split point self-centers and reduces thrust, minimizing walking on entry
• Web-thinned parallel web lowers cutting force on harder alloy workpieces
• Screw machine length at 2.125 inches OAL provides rigidity in confined setups
• Right-hand, two-flute spiral design for efficient chip evacuation
• Diameter tolerance held to +0.0000 to -0.0007 inches for consistent, accurate holes
• Conforms to ASME B94.11M and DIN 1897 specifications

Compatibility

Designed for use in standard drill chucks, drill presses, turret lathes, and CNC machining centers accepting a 0.166-inch straight cylindrical shank. Suitable for drilling alloy steel and aluminum workpieces.

Installation Notes

Secure the shank fully in a properly sized chuck before operation and confirm chuck key is removed before powering on. Use appropriate cutting fluid or coolant for the workpiece material to maximize bit life, especially in alloy steel. Inspect the cutting edges for wear or chipping before each use; a dull or chipped cobalt bit should be resharpened by a qualified tool grinder or replaced. Follow shop safety procedures and applicable OSHA machine guarding requirements when operating drill presses or lathes.
