Kennametal 4124962 Screw Machine Drill Bit 2mm Carbide

Product Description

The KENNAMETAL 4124962 is a screw machine length drill bit engineered for high-performance drilling in demanding materials. Built from solid carbide with a TiN tip coating, it delivers extended tool life and heat resistance in applications where standard high-speed steel bits fall short. The 140-degree split point reduces thrust and walking at entry, making it well suited for tight-tolerance work. At 2.00 mm in diameter with an overall length of 58.00 mm (2.2835 inches), this bit fits compact drilling setups where stub length is required. Coolant-through design supports chip evacuation and thermal management during deep or interrupted cuts. Licensed machinists, toolroom technicians, and production drilling operators are the primary installers.

This drill bit is designed for use in screw machine operations, CNC drilling centers, and manual drill press setups where short, rigid tooling is required. Primary target workpiece materials include stainless steel, cast iron, and high-temperature alloys — materials that demand carbide substrate and aggressive point geometry to achieve clean, accurate holes. The straight cylindrical shank accommodates standard drill chucks and collet systems. Series B051A follows DIN 6535 and DIN 6537 standards, making it compatible with metric toolholding systems common in precision machining environments.

Key Features

• Solid carbide construction for rigidity and wear resistance in hard and abrasive materials
• TiN tip coating reduces friction and extends cutting edge life at the drill point
• 140-degree drill point angle minimizes entry thrust and self-centers on flat surfaces
• Coolant-through design improves chip evacuation and controls heat in deep-hole applications
• Tapered web configuration adds core strength while maintaining chip clearance
• Meets DIN 6535 and DIN 6537 standards for consistent metric toolholding compatibility

Compatibility

Designed for use in standard straight-shank drill chucks and collet holders conforming to DIN 6535 and DIN 6537 specifications. Suited for drilling stainless steel, cast iron, and high-temperature alloys in screw machine and CNC drilling applications within the Series B051A product family.

Installation Notes

Installation is performed by machinists or toolroom technicians in a machine tool environment. Ensure the spindle is fully stopped and the machine is locked out before changing tooling. Secure the straight cylindrical shank firmly in a properly sized collet or drill chuck to prevent runout. Verify coolant-through lines are clear and pressurized before engaging the cut to protect the cutting edge and promote chip evacuation.
