Value Collection 01195833 Screw Machine Drill Bit 6.50mm

Product Description

The VALUE COLLECTION 01195833 is a screw machine length cobalt drill bit designed for drilling in metals and other hard materials where a shorter, more rigid bit is required. With a 6.50 mm (0.2559 inch) diameter and a 135-degree split point, this bit starts on contact without walking, reducing the need for a center punch. The cobalt construction with a straw finish handles elevated cutting temperatures better than standard high-speed steel. The straight shank accepts standard drill chucks. This bit is suited for machinists, maintenance technicians, and fabricators working in production and job-shop environments.

Screw machine length drill bits are used when a standard jobber-length bit would flex or chatter due to reach. The shortened flute and overall length provide added rigidity in drill presses, CNC machining centers, and mill setups. The 6.50 mm diameter falls within the 6.50 to 8.00 mm size range, making it a common selection for tapping prep, clearance holes, and close-tolerance work in steel, stainless, cast iron, and similar materials. This bit is sold individually and is appropriate for both production drilling and one-off repair work.

Key Features

• 6.50 mm (0.2559 inch) diameter with 135-degree split point for self-starting, reduced thrust drilling
• Cobalt tool material rated for heavy-duty use in hard and abrasive metals
• Straw finish indicates heat-treated cobalt construction suitable for elevated-temperature cutting
• Screw machine (stub) length at 70.00 mm (2.756 inches) OAL provides rigidity in tight setups
• 31.00 mm flute length with regular spiral and regular flute geometry for efficient chip evacuation
• Right-hand cutting direction, straight shank, 2-flute design compatible with standard drill chucks

Compatibility

Designed as a screw machine length replacement or stock drill bit for use in standard drill chucks, drill presses, and CNC spindles accepting straight-shank tooling in the 6.50 to 8.00 mm size range.

Installation Notes

This bit is installed by a machinist or maintenance technician into a standard drill chuck or collet rated for the straight shank diameter. Secure the shank fully in the chuck before operation and confirm runout is within acceptable limits for the application. Use appropriate cutting fluid or coolant when drilling steel or stainless to extend tool life, noting this bit does not have through-coolant capability. Follow shop safety practices including eye protection and secure workpiece clamping before drilling.
