Accupro 4500198 Solid Carbide Jobber Drill 9mm 140 Deg

Product Description

The ACCUPRO 4500198 is a solid carbide jobber-length drill bit with a diamond coating, designed for demanding precision drilling applications. It features a 9.00 mm diameter, a 140-degree proprietary point angle, and a right-hand cutting direction with a regular spiral flute configuration. The diamond coating provides the surface hardness required to cut through abrasive, difficult-to-machine materials without premature wear. This bit is installed by machining professionals and CNC operators working in aerospace, composites fabrication, and advanced manufacturing environments.

This drill is specifically engineered for carbon fiber reinforced polymer (CFRP) materials, where abrasion resistance and clean exit-hole quality are critical. The solid carbide substrate paired with the diamond coating makes it well suited for composite layups and laminated stack materials commonly encountered in aerospace and industrial fabrication. The straight cylindrical shank with a 10 mm shank diameter seats securely in standard drill chucks and collet holders used on CNC machining centers and precision drilling equipment. Coolant-through capability is not supported on this bit.

Key Features

• Diamond coating for exceptional abrasion resistance when drilling CFRP and composite materials
• 140-degree proprietary point angle reduces delamination and exit-side breakout
• Solid carbide construction maintains rigidity and edge integrity under high-speed conditions
• Regular spiral flute geometry promotes consistent chip evacuation over a 61.00 mm flute length
• Right-hand cutting direction compatible with standard CNC spindle rotation
• Straight cylindrical shank seats in standard chucks and collet systems without modification

Compatibility

Designed for use in CNC machining centers and precision drilling equipment where a straight-shank jobber drill in the 9.00 mm to 10.00 mm drill size range is required. Primary workpiece material compatibility is CFRP and similar composite materials per supplier specification.

Installation Notes

Installation and operation should be performed by qualified machinists or CNC technicians. Secure the straight cylindrical shank fully into the collet or chuck before operation and verify runout before cutting. Power down and de-energize the spindle completely before changing or inspecting the bit. Do not use this bit on materials outside its rated application, as misapplication will rapidly degrade the diamond coating and compromise tool life.
