Cleveland C14519 Screw Machine Drill Bit 53 Cobalt

Product Description

The CLEVELAND C14519 is a screw machine length drill bit designed for high-speed, precision drilling in demanding production environments. Built from M42 cobalt high-speed steel, it is rated for heavy-duty cutting and handles tough materials including alloy steel and aluminum. The 135-degree split point with web thinning reduces walking and lowers thrust requirements at entry. At 0.0595 inches in diameter (wire size 53) and 1.625 inches overall length, this short-length geometry provides rigidity and minimizes deflection in close-quarters drilling. Licensed machinists, tool-and-die workers, and maintenance technicians are the primary users of this bit.

The C14519 is intended for production drilling in CNC machining centers, drill presses, and manual machines where stub-length stiffness is an advantage. Its straight cylindrical shank seats directly into standard drill chucks and collet holders. The right-hand spiral flutes evacuate chips efficiently in both ferrous and non-ferrous workpiece materials, including alloy steel and aluminum. Conformance to ASME B94.11M and DIN 1897 specifications ensures dimensional consistency across the lot.

Key Features

• M42 cobalt construction rated for heavy-duty cutting of alloy and aluminum workpieces
• 135-degree conventional point with web thinning reduces entry thrust and self-centers on contact
• Screw machine (stub) length at 1.625 inches OAL delivers maximum rigidity and reduced deflection
• Straight cylindrical shank at 0.0595 inches diameter fits standard chucks and collets
• Right-hand cut with 2 regular spiral flutes for consistent chip evacuation
• Meets ASME B94.11M and DIN 1897 specifications for dimensional accuracy

Compatibility

Designed as an OEM-style screw machine length drill bit compatible with standard drill chucks and collet systems accepting a 0.0595-inch straight cylindrical shank.

Installation Notes

Installation and use should be performed by qualified machinists or maintenance technicians familiar with rotating cutting tools. Secure the shank fully in the chuck or collet and verify runout before cutting. Always power down and de-energize the machine spindle before changing or inspecting bits. Use appropriate cutting fluid for the workpiece material to maximize tool life and hole quality.
