Accupro 63310072 Carbide Jobber Drill Bit 3mm Altin

Product Description

The ACCUPRO 63310072 is a solid carbide jobber-length drill bit engineered for precision drilling in hard and abrasive materials. It features an AlTiN (aluminum titanium nitride) coating that extends tool life by resisting heat buildup at high cutting speeds. The 140-degree split point with web thinning reduces thrust force and improves centering without a pilot hole. With a 3 mm diameter and 50 mm overall length, this bit suits light-duty production drilling in tool steels, stainless steel, cast iron, and similar materials. It is used by machinists, tool and die workers, and maintenance technicians working on CNC machines and manual drill presses.

This drill bit is sized at 3 mm with a matching 3 mm straight-cylindrical shank, making it compatible with standard drill chucks and collet systems that accept that shank diameter. The regular spiral flute geometry and 4xD flute-to-diameter ratio support efficient chip evacuation in most common drilling applications. It is suited to both production-floor and job-shop environments where consistent hole quality in ferrous and non-ferrous metals is required. The right-hand cut is standard for conventional drill press and CNC spindle rotation.

Key Features

• Solid carbide construction for rigidity and wear resistance in hard materials
• AlTiN coating improves heat resistance and extends cutting life at elevated speeds
• 140-degree notched point with web thinning reduces entry force and improves hole accuracy
• 3 mm straight-cylindrical shank fits standard chucks and collet holders
• Regular spiral flute with 4xD ratio promotes reliable chip clearance
• Right-hand cut matches standard CNC and manual spindle rotation

Compatibility

Designed as a jobber-length replacement or production drill bit for use in any drill press, CNC machining center, or handheld drill with a chuck or collet accepting a 3 mm straight-cylindrical shank.

Installation Notes

This bit is installed by machinists and CNC operators. Ensure the machine spindle is fully stopped and locked out before changing tooling. Seat the shank fully and evenly in the chuck or collet and confirm it is concentric before beginning a cut. Solid carbide tooling is brittle and may chip if subjected to side loading or excessive vibration, so use appropriate feed and speed settings for the workpiece material.
