Accupro 4500162 Solid Carbide Jobber Drill 3.00 Mm

Product Description

The ACCUPRO 4500162 is a solid carbide jobber-length drill bit designed for high-performance drilling in demanding materials. It features a 3.00 mm diameter (0.1181 inches) cutting edge, a 140-degree split point geometry, and a TiAlN coating that extends tool life by resisting heat and wear at elevated cutting speeds. The R-thinned web reduces thrust and improves chip evacuation at the point. With an overall length of 66.00 mm (2.5984 inches) and a flute length of 28.00 mm (1.1024 inches), this bit suits precision drilling in tight-tolerance applications. A coolant-through design delivers cutting fluid directly to the tip, making it well suited for machining centers and CNC setups. Machinists and tool-and-die professionals are the primary users of this tooling.

This drill bit is rated for primary use in stainless steel, a material class that demands high cutting edge integrity and effective heat management. The TiAlN coating and solid carbide substrate handle the work-hardening tendencies common to austenitic stainless alloys. The 5xD flute-to-diameter ratio supports deeper hole drilling relative to bit diameter. Applications include fabrication shops, production machining, medical device manufacturing, food service equipment repair, and aerospace component work where small-diameter precision holes in hard materials are required. A straight cylindrical shank sized at 6 mm fits standard collet chucks and drill chucks on CNC machines and manual mills.

Key Features

• Solid carbide construction delivers rigidity and wear resistance beyond high-speed steel alternatives
• TiAlN coating provides thermal protection and extends tool life in stainless steel and other hard alloys
• 140-degree point angle reduces thrust and improves self-centering on hard materials
• R-thinned web minimizes chisel edge contact and lowers entry force
• Coolant-through design channels fluid directly to the cutting tip for chip clearing and heat control
• DIN specification conformance ensures dimensional consistency for repeatable toolholder fit

Compatibility

Designed for use in CNC machining centers, manual mills, and drill presses equipped with collet chucks or drill chucks accepting a 6 mm straight cylindrical shank. Intended for drilling stainless steel as the primary workpiece material; also suitable for other ferrous alloys and hard materials where TiAlN-coated carbide tooling is specified.

Installation Notes

Installation and use of precision carbide tooling should be performed by qualified machinists familiar with speeds, feeds, and coolant requirements for the target material. Ensure the machine spindle and chuck are free of runout before seating the shank, as carbide is brittle and sensitive to lateral loading. Verify coolant-through passages are clear and system pressure is adequate before beginning a drilling cycle. Do not use this bit in a hammer drill or handheld drill driver.
