Precision Twist Drill 5996038 Cobalt Drill Bit 0.185 in

Product Description

The PRECISION TWIST DRILL 5996038 is a screw machine length cobalt drill bit designed for drilling into hard and difficult-to-machine materials. Built to ANSI standards, it features a 135-degree split point that reduces walking and requires less starting force than a conventional point. The M41CO cobalt construction provides heat resistance for sustained performance in high-speed or interrupted-cut applications. At 0.185 inches in diameter with an overall length of 2-3/16 inches and a flute length of 1-1/8 inches, this bit fits standard straight-cylindrical chuck applications. It is suited for machinists, maintenance technicians, and metalworking professionals who need reliable performance in hard material drilling.

The 5996038 is built for use in screw machine and production drilling operations where compact overall length improves rigidity and reduces deflection. Its right-hand spiral flute geometry with a 2.5xD flute-to-diameter ratio and tapered web configuration supports efficient chip evacuation in hard ferrous and non-ferrous materials. This bit is appropriate for use in CNC machining centers, drill presses, and hand-held power tools wherever a short-length, high-performance cobalt bit is needed.

Key Features

• M41 cobalt tool material rated for heavy-duty, high-performance drilling in hard materials
• 135-degree split point with web thinning reduces thrust force and eliminates center punch requirements
• Screw machine length body provides increased rigidity and reduced deflection versus jobber-length bits
• Right-hand spiral flute with 2.5xD ratio promotes effective chip removal
• Tapered web configuration adds core strength along the flute length
• Meets ANSI specification standards for dimensional consistency

Compatibility

Designed as a standard screw machine length drill bit for use in straight-cylindrical chucks compatible with 0.185-inch shank tooling in the 0.1500 to 0.2000 inch diameter range of the M41CO series.

Installation Notes

Installation and use of this drill bit should be performed by qualified machinists or trade professionals familiar with proper chuck-mounting procedures. Verify spindle speed and feed rate are appropriate for the workpiece material before drilling. Secure the workpiece firmly and confirm the chuck is fully tightened before operation. Coolant-through is not supported on this bit; use external cutting fluid when drilling hard materials to extend tool life.
