Accupro A-6140050R Spotting Drill 0.5mm 2-flute Carbide

Product Description

The ACCUPRO A-6140050R is a solid carbide spotting drill designed to create precise center marks and chamfered starter holes for follow-on drilling operations. Built with a 120-degree drill point angle and a 0.5mm (0.0197 inch) cutting diameter, it produces accurate spot locations that guide twist drills and reduce walking on flat or curved surfaces. The 2-flute spiral flute geometry supports chip evacuation in short spotting passes. At 30mm (1.1811 inches) overall length with a 1.5mm (0.0591 inch) straight-cylindrical shank, this tool fits standard collets and chucks used in CNC machining centers and manual drill presses. The bright, uncoated finish suits general-purpose spotting across a range of workpiece materials.

This spotting drill is suited to production machining, toolroom, and job-shop environments where consistent hole location accuracy is required. The single-ended, right-hand cut configuration makes it a straightforward drop-in for standard CNC and manual setups. Its compact overall length and small cutting diameter target fine-pitch hole patterns common in electronics, medical device, and precision instrument manufacturing applications.

Key Features

• 120-degree drill point angle for accurate center spotting and chamfer generation
• 0.5mm cutting diameter with 1.9mm flute length for shallow, precise spot holes
• Solid carbide construction provides rigidity and wear resistance in general-purpose applications
• 2-flute spiral geometry supports chip clearance during spotting passes
• Bright/uncoated finish compatible with a broad range of workpiece materials
• Straight-cylindrical shank fits standard collets, ER chucks, and drill chucks

Compatibility

Designed as a general-purpose spotting drill compatible with CNC machining centers, drill presses, and manual mills equipped with collets or chucks accepting a 1.5mm straight-cylindrical shank.

Installation Notes

Installation and use should be performed by a qualified machinist or CNC operator. Ensure the machine spindle is fully stopped and locked out before inserting or removing the tool from the collet or chuck. Confirm collet size matches the 1.5mm shank diameter before clamping to prevent tool runout or pullout. Set spindle speed and feed rate according to the workpiece material and machine capability; consult tooling charts for appropriate cutting parameters.
