Accupro 4500206 Carbide Drill Bit 10 Mm Diamond 140 Deg

Product Description

The ACCUPRO 4500206 is a solid carbide jobber length drill bit engineered for high-performance drilling in demanding production and shop environments. The bit measures 10 mm in diameter with a 140-degree split point and an overall length of 103 mm. A diamond coating reduces friction and extends tool life when cutting abrasive materials such as composites, ceramics, and hardened alloys. Two spiral flutes in a regular helix pattern evacuate chips efficiently throughout the cut. This bit is installed and operated by machinists, tool-and-die tradespeople, and precision fabricators working with CNC machining centers, drill presses, and handheld power tools.

The 4500206 is suited for production drilling applications where a standard high-speed steel bit would wear prematurely. Its solid carbide construction and diamond coating make it a strong choice for drilling carbon fiber reinforced polymers, glass fiber composites, hard plastics, and non-ferrous metals. The straight-cylindrical shank accepts standard drill chucks without adapters, making tool changes straightforward on most machine spindles. The 5xD flute-to-diameter ratio supports drilling to moderate depths without frequent retract cycles.

Key Features

• Solid carbide construction for rigidity and wear resistance in hard or abrasive materials
• Diamond coating extends cutting life and reduces heat buildup at the cutting edge
• 140-degree point angle improves self-centering and reduces thrust on entry
• Two regular-spiral flutes provide efficient chip evacuation throughout the bore
• Straight-cylindrical shank seats securely in standard 3-jaw and collet-style drill chucks
• DIN specification designation ensures dimensional conformance to recognized tooling standards

Compatibility

Designed as a high-performance replacement jobber drill for applications requiring a 10 mm straight-shank carbide bit conforming to DIN specification in the 10.00 mm to 12.50 mm drill size range.

Installation Notes

Installation and operation should be performed by qualified machinists or tooling technicians familiar with rotating cutting tools. Secure the shank fully in the chuck or collet before starting the spindle, and verify runout is within acceptable limits for the application. Operate at manufacturer-recommended speeds and feeds for carbide tooling in the specific workpiece material. Diamond-coated carbide bits are brittle under lateral load - avoid side pressure and do not use for slot milling or angular entry cuts.
