Precision Twist Drill 6000650 Jobber Drill 2.80mm Cobalt

Product Description

The PRECISION TWIST DRILL 6000650 is a 2.80 mm (0.1102 inch) cobalt high-speed steel jobber-length drill bit designed for general-purpose drilling in steel and other metals. It features a 135-degree split point with web thinning, which reduces walking on entry and lowers the thrust required to start a hole. The straw oxide/bronze coating provides a degree of lubricity and heat resistance during cutting. At 2-13/32 inches overall length with a 1-19/64 inch flute, this is a standard jobber-length geometry suitable for production and maintenance drilling applications. Two right-hand regular-spiral flutes evacuate chips efficiently from the cut zone.

This drill bit is intended for drilling steel, cast iron, non-ferrous metals, and similar materials, as indicated by the primary workpiece material codes P, M, K, N, and S per DIN 338 classification. The 2ACO series targets heavy-duty general-purpose work where a cobalt grade provides better heat resistance than standard M2 HSS. Typical install scenarios include machine shop production, field maintenance, and fabrication work where consistent hole quality in metal is required. The straight cylindrical shank fits standard drill chucks across a range of machines.

Key Features

• Cobalt high-speed steel construction for improved heat and wear resistance versus standard HSS
• 135-degree split point with web thinning reduces walking and lowers drilling thrust
• Straw oxide finish adds lubricity and mild corrosion protection
• Regular spiral flute geometry promotes reliable chip evacuation in metal drilling
• Straight cylindrical shank fits standard 3-jaw chucks and collet holders
• Meets DIN 338 and ANSI standards for jobber-length drill geometry

Compatibility

Designed as an OEM-style replacement or direct-use jobber drill for general metal drilling applications in any standard drill press, CNC machining center, or hand-held drill with a chuck capable of accepting a 2.80 mm (0.1102 inch) straight shank.

Installation Notes

Installation is performed by machinists and maintenance technicians using a standard keyed or keyless drill chuck. Ensure the machine is fully powered down and the chuck is secure before beginning any bit change. Apply appropriate cutting fluid when drilling steel to extend tool life and improve hole finish. Do not exceed the recommended maximum drilling depth of 1.2992 inches without retracting to clear chips.
