Hertel 89321350 Screw Machine Drill Bit Wire 6 Hss

Product Description

The HERTEL 89321350 is a screw machine length drill bit designed for general-purpose drilling in metal, wood, and plastics. Built from high-speed steel (HSS) with a bright, uncoated finish, this bit holds up under standard shop conditions without additional surface treatment. The 118-degree point angle makes it a versatile choice for flat-entry drilling across a wide range of workpiece materials. At 2.375 inches overall length with a 1.25-inch flute length, the screw machine format provides added rigidity over jobber-length bits, reducing deflection in short-hole drilling applications. Wire size 6 corresponds to a decimal diameter of 0.2040 inches.

This drill bit is suited for production drilling, machine shop work, and general fabrication tasks. Screw machine length bits are commonly used in CNC machines, drill presses, and turret lathes where a shorter, stiffer cutting tool reduces runout and improves hole accuracy. The right-hand cut makes it compatible with standard spindle rotation on virtually all drilling equipment. It ships as a single unit, making it a practical replacement or addition to existing drill index sets.

Key Features

• 118-degree split-point-compatible angle for general-purpose flat-entry drilling
• High-speed steel construction for durability across metal, wood, and plastic substrates
• Screw machine length body provides increased rigidity and reduced deflection versus jobber-length bits
• Bright uncoated finish suitable for standard drilling without coolant requirements
• Right-hand cut compatible with all standard drill press and CNC spindle rotation

Compatibility

Designed as a general-purpose screw machine length drill bit suitable for use in drill presses, CNC machining centers, turret lathes, and hand-held drilling equipment that accepts standard round-shank bits in the 0.2040-inch diameter range.

Installation Notes

Installation and use should be performed by machinists or qualified trade professionals familiar with rotating cutting tools. Ensure the drill chuck is fully tightened and the workpiece is securely clamped before operation. Always power down and de-energize drilling equipment before changing bits. Follow applicable shop safety standards and wear appropriate eye protection when operating drilling machinery.
