Hertel 89321665 Screw Machine Drill Bit Wire 17 Hss

Product Description

The HERTEL 89321665 is a screw machine length drill bit designed for general-purpose metal drilling in production and maintenance environments. Built from high-speed steel with a bright uncoated finish, it cuts a 0.1730 inch diameter hole at wire size 17. The 118-degree split-point angle suits a wide range of common materials including mild steel, aluminum, and plastics. Its shortened overall length of 2.1875 inches provides added rigidity compared to jobber-length bits, reducing deflection in screw machine, drill press, and CNC applications. Machinists, tool and die technicians, and maintenance mechanics are the primary users of this style of bit.

This drill bit is suited for light-to-medium duty production drilling where a compact, rigid tool is preferred over standard jobber length. The screw machine length body fits closely into turret heads and multi-spindle fixtures. Applications include drilling pilot holes, clearance holes, and through-holes in sheet metal, structural steel, aluminum stock, and thermoplastic components. The right-hand cutting direction is compatible with standard CNC machining centers, drill presses, and handheld power tools configured for conventional rotation.

Key Features

• Wire size 17 diameter at 0.1730 inches for precise hole sizing in production work
• 118-degree point angle provides reliable self-centering on flat and curved surfaces
• Screw machine length body at 2.1875 inches overall reduces deflection and chatter
• High-speed steel construction maintains cutting edge integrity across a range of workpiece materials
• Bright uncoated finish allows visual wear inspection during tool life monitoring
• Right-hand cut compatible with all standard drill spindles and machine tool setups

Compatibility

Designed as a general-purpose screw machine length drill bit for use in standard drill chucks accepting wire gauge tooling. Fits any machine or handheld drill accepting a straight shank tool in the 0.1730 inch diameter range.

Installation Notes

Installation of this drill bit should be performed by a qualified machinist or maintenance technician. Ensure the drill press, turret lathe, or CNC spindle is fully powered down and locked out before changing tooling. Seat the straight shank fully and concentrically in the chuck or collet to prevent runout. Use cutting fluid appropriate to the workpiece material to extend tool life and reduce heat buildup.
