Kennametal 4150160 Screw Machine Drill Bit Size 30

Product Description

The KENNAMETAL 4150160 is a solid carbide screw machine length drill bit designed for high-performance drilling in demanding production environments. Built to Series B041A and conforming to DIN 6537K specifications, this wire gauge Size 30 bit measures 0.1285 inches (3.26 mm) in diameter with a 140-degree point angle for aggressive penetration and reduced thrust. The overall length is 2.44 inches (62.00 mm), making it well-suited for short-hole, high-cycle applications where rigidity and repeatability matter. A titanium nitride (TiN) tip coating extends cutting edge life on abrasive workpiece materials. Licensed machinists, tool room technicians, and production drilling operators are the primary users of this bit.

This drill bit is engineered for cutting steel, stainless steel, cast iron, and high-temperature alloys in screw machine and CNC drilling operations. The screw machine length format provides enhanced stability over jobber-length bits, reducing deflection in tight-tolerance hole applications. With a straight cylindrical shank of 0.2362 inches (6.00 mm) diameter and a flute length of 0.787 inches (20.00 mm), this bit fits standard collets and chucks used in turret lathes, screw machines, and machining centers. Maximum drilling depth is 0.551 inches (14.00 mm).

Key Features

• Solid carbide construction for rigidity and wear resistance in ferrous and high-temp alloy materials
• TiN tip coating reduces friction and extends cutting edge life
• 140-degree point angle minimizes thrust and improves self-centering on entry
• Screw machine length body (2.44 inches OAL) increases stiffness over jobber-length alternatives
• Tapered web configuration improves chip evacuation through the 2-flute regular spiral design
• Conforms to DIN 6535 and DIN 6537 standards for dimensional consistency

Compatibility

Designed as an OEM-style replacement and production drill for use in screw machines, turret lathes, and CNC machining centers accepting a 0.2362-inch (6.00 mm) straight cylindrical shank. Compatible with workpiece materials including steel, stainless steel, cast iron, and high-temperature alloys per Series B041A application specifications.

Installation Notes

Installation should be performed by a qualified machinist or tool room technician familiar with cutting tool setup procedures. Ensure the spindle and machine are fully powered down and locked out before changing tooling. Seat the straight shank fully in the collet or chuck and verify runout is within tolerance before commencing a drilling cycle. Do not exceed the maximum drilling depth of 0.551 inches without retracting to clear chips, as this is a non-coolant-through design.
