Value Collection 01195957 Cobalt Screw Machine Drill Bit 11mm

Product Description

The VALUE COLLECTION 01195957 is a cobalt screw machine length drill bit designed for heavy-duty metal drilling in tight-clearance applications. It measures 11.00 mm (0.4331 inches) in diameter with an overall length of 95.00 mm (3.74 inches) and a flute length of 47.00 mm (1.85 inches). The 135-degree split point geometry reduces walking on entry and requires less thrust than a standard 118-degree point. The straw finish indicates heat treatment without a dedicated coating layer. This bit is suited for machinists, maintenance technicians, and metalworking trades working with hard or work-hardening materials such as stainless steel, cast iron, and high-strength alloys.

Screw machine length drill bits are shorter than jobber-length bits, providing increased rigidity and reduced deflection when drilling in drill presses, CNC machines, turret lathes, and screw machines. This bit is a common choice for production drilling environments where hole accuracy and tool life are priorities. The right-hand cutting direction is standard for conventional drilling setups. It falls within the 11.00 mm to 13.50 mm size range category and carries UNSPSC code 23241635.

Key Features

• 11.00 mm diameter with 135-degree split point for reduced entry thrust and self-centering action
• Cobalt construction for improved heat resistance and durability in hard metals
• Screw machine length body (95.00 mm OAL) delivers greater rigidity than jobber-length alternatives
• 2-flute regular spiral design for efficient chip evacuation
• Straight shank fits standard drill chucks without adapters
• Heavy-duty grade rating for demanding production and maintenance applications

Compatibility

Designed for use in standard straight-shank drill chucks on drill presses, CNC machining centers, turret lathes, and handheld power drills. Compatible with drill presses and machines accepting straight-shank tooling in the 11.00 mm to 13.50 mm size range.

Installation Notes

Installation and use of this drill bit should be performed by qualified machinists or maintenance technicians familiar with proper speeds and feeds for cobalt tooling. Ensure the machine spindle is fully stopped and de-energized before changing bits. Secure the shank firmly in the chuck to the full depth of the chuck jaws to prevent slippage. Use appropriate cutting fluid or coolant for the workpiece material to extend tool life, noting this bit does not support coolant-through delivery.
