Kennametal 2213700 Screw Machine Drill Bit 4.30mm Carbide

Product Description

The KENNAMETAL 2213700 is a solid carbide screw machine length drill bit designed for high-productivity drilling in ferrous materials. It carries a multilayer TiAlN coating that resists heat buildup and extends cutting life in demanding applications. The 140-degree split point geometry reduces thrust and improves centering without a pilot hole. At 66.00 mm overall length with a 24.00 mm flute length, this stub-length drill is built for rigidity in short-reach operations. A 6.00 mm straight cylindrical shank seats securely in standard drill chucks and collet systems. Licensed machinists, toolroom technicians, and CNC operators working on precision components will find this bit appropriate for production-level use.

This drill bit is intended for screw machine and CNC drilling applications where a rigid, short-length tool reduces deflection and improves hole accuracy. It is rated for use in primary workpiece materials including cast iron and steel. The 4.30 mm diameter corresponds to 0.1693 decimal inch, placing it in the 3.50 to 5.00 mm size range per DIN 6537K specification. Web thinning with a parallel web configuration lowers cutting forces and aids chip evacuation in deep-hole passes up to 17.00 mm. Right-hand spiral flute geometry promotes consistent chip flow in through-hole and blind-hole configurations.

Key Features

• Solid carbide construction provides stiffness and heat resistance at elevated cutting speeds
• Multilayer TiAlN coating extends tool life in cast iron and steel applications
• 140-degree standard point angle self-centers and reduces entry burring
• Web-thinned parallel web lowers thrust and supports chip evacuation
• Screw machine length body minimizes deflection for tighter positional tolerances
• Meets DIN 6537K specification for dimensional consistency and interchangeability

Compatibility

Designed as an OEM-style replacement or direct substitute for screw machine length carbide drills in the 3.50 to 5.00 mm range per DIN 6537K. Fits standard straight-shank drill chucks and collet holders accepting a 6.00 mm shank diameter. Part of KENNAMETAL Series B966.

Installation Notes

Installation should be performed by a qualified machinist or CNC toolroom technician. Power down or estop the machine and confirm spindle is fully stopped before changing tooling. Seat the straight cylindrical shank fully into the collet or chuck and confirm runout with a dial indicator before beginning production cuts. Follow machine manufacturer torque specifications for collet nut tightening and verify drilling depth stop settings before engaging the workpiece.
