Accupro A-6140045R Spotting Drill 0.45mm Solid Carbide

Product Description

The ACCUPRO A-6140045R is a 2-flute solid carbide spotting drill designed to create precise starter holes for follow-on drilling operations. With a 120-degree drill point angle and a 0.45 mm (0.0177 inch) cutting diameter, this tool establishes accurate hole locations while minimizing walking and runout. The overall length is 30 mm (1.1811 inches), making it suited for compact setups and close-tolerance work. The bright/uncoated finish keeps the tool ready for use without additional prep. Machinists and tool-and-die professionals install this type of spotting drill on CNC machining centers and manual drill presses where hole position accuracy is critical.

This spotting drill is intended for general-purpose spotting applications across a range of workpiece materials. The straight cylindrical shank and right-hand spiral flutes make it compatible with standard collet chucks and drill chucks used in production and job-shop environments. The 1.5 mm flute length and 1.5 mm shank diameter suit fine-detail work and small-bore applications where a standard-diameter drill would be impractical. It is sold individually with a minimum order quantity of 10 units, making it appropriate for shop stock replenishment or tooling kits.

Key Features

• 120-degree drill point angle for accurate hole spotting and center-starting
• 0.45 mm cutting diameter for fine-pitch and small-bore spotting work
• Solid carbide construction provides rigidity and wear resistance in general-purpose applications
• Bright/uncoated finish — no coating prep required before use
• Right-hand, spiral flute geometry with straight cylindrical shank for standard chuck compatibility
• Single-ended design; 30 mm overall length suits compact machine setups

Compatibility

Designed as a general-purpose spotting drill for use in standard collet chucks or drill chucks on CNC machining centers and drill presses where a straight cylindrical shank and 1.5 mm shank diameter are accepted.

Installation Notes

Installation and use of this tool should be performed by qualified machinists familiar with small-diameter carbide tooling. Ensure the spindle and work-holding fixture are properly secured and that runout is minimized before engaging the tool, as carbide is brittle and susceptible to breakage from lateral loading. Confirm chuck or collet bore matches the 1.5 mm shank diameter before clamping. Always follow the machine manufacturer's speed and feed guidelines for solid carbide spotting drills at this diameter range.
