Accupro 4500240 Solid Carbide Jobber Drill 18 Mm Tialn

Product Description

The ACCUPRO 4500240 is a solid carbide jobber-length drill bit designed for high-performance drilling in demanding materials. It measures 18 mm (0.7087 inches) in diameter with an overall length of 143 mm (5.63 inches) and a flute length of 93 mm (3.66 inches). The 140-degree split point and R-thinned web reduce entry force and improve centering on hard surfaces. A TiAlN coating adds heat resistance and extends tool life under aggressive cutting conditions. This drill is intended for use by machinists, tool-and-die professionals, and precision metalworking shops running CNC or manual drilling operations.

This drill bit is optimized for cutting stainless steel and other difficult-to-machine ferrous and non-ferrous alloys. The 5xD flute-to-diameter ratio supports deeper hole applications within the jobber range. Coolant-through capability allows internal delivery of cutting fluid directly to the tip, making it well suited for production environments where heat buildup and chip evacuation are primary concerns. The straight cylindrical shank seats into standard drill chucks and collet holders without modification.

Key Features

• Solid carbide construction for rigidity and wear resistance in hard materials
• TiAlN coating for elevated heat resistance and extended tool life
• 140-degree point angle with R-thinned web for improved centering and reduced thrust
• Coolant-through design for internal cutting fluid delivery
• Right-hand, regular spiral flute geometry for efficient chip evacuation
• Straight cylindrical shank compatible with standard chucks and collet systems

Compatibility

Designed as a high-performance OEM-style jobber drill for use in CNC machining centers, drill presses, and manual lathes equipped with standard straight-shank toolholders. Optimized for primary workpiece material: stainless steel.

Installation Notes

Installation and operation should be performed by qualified machinists familiar with carbide tooling. Ensure the machine spindle and toolholder are clean and within tolerance before seating the shank. Carbide is brittle — avoid side loading, interrupted cuts without proper support, or over-tightening chuck jaws that can crack the shank. When using coolant-through capability, confirm the machine spindle supplies adequate pressure and that coolant lines are clear before beginning the cut.
