Precision Twist Drill 6000654 Jobber Drill 2.90mm Cobalt

Product Description

The PRECISION TWIST DRILL 6000654 is a 2.90 mm cobalt jobber-length drill bit designed for general-purpose drilling in ferrous and non-ferrous metals. Built to DIN 338 and ANSI standards, it features a 135-degree split point for reduced walking and faster penetration without a center punch. The straw oxide finish provides mild lubricity and heat resistance during cutting. The web-thinned, tapered web construction reduces thrust load at the cutting edge, making it well suited for hand-held and machine drilling in production or maintenance environments. Licensed trades and machining professionals working in fabrication, mechanical contracting, and industrial maintenance will find this bit a reliable daily-use tool.

This bit is rated for drilling steel and is assigned primary workpiece material codes P, M, K, N, and S, covering carbon steels, stainless steels, cast irons, non-ferrous alloys, and heat-resistant superalloys. With an overall length of 2-13/32 inches and a flute length of 1-19/64 inches, it fits standard drill chucks and drill press spindles without adapters. The straight cylindrical shank diameter matches the bit diameter at 2.90 mm (0.1142 inches), keeping setup simple. It is a heavy-duty grade bit intended for shop and field use where a consistent, accurate hole in metal is required.

Key Features

• Cobalt construction for improved heat resistance and hardness retention when drilling tough steels
• 135-degree split point reduces bit walking and lowers required feed pressure
• Straw oxide finish adds surface lubricity and light corrosion protection
• Web-thinned tapered web reduces axial thrust at depth
• DIN 338 and ANSI standard geometry ensures broad tool compatibility
• Right-hand spiral flute efficiently evacuates chips during through-hole drilling

Compatibility

Designed as an OEM-style replacement or direct substitution jobber drill bit for use in standard 3-jaw drill chucks, drill presses, CNC machining centers, and hand drills accepting straight-shank bits in the 2.00 mm to 3.00 mm diameter range.

Installation Notes

Installation is performed by machinists, maintenance technicians, or licensed mechanical contractors. Secure the straight shank fully in the chuck jaws and verify concentricity before drilling. Always power down and lock out the machine before changing bits. Use appropriate cutting fluid or coolant when drilling steel to extend bit life and maintain dimensional accuracy.
