Hertel 61698635 Screw Machine Drill Bit 3/4 in Hss

Product Description

The HERTEL 61698635 is a screw machine length drill bit designed for high-volume drilling in metal, wood, and general-purpose materials. Built from high-speed steel with an oxide coating, it delivers reliable wear resistance in production and maintenance environments. The 3/4-inch diameter bit features a 118-degree standard point angle, a 2-flute spiral configuration, and a straight cylindrical shank for secure chuck engagement. At 5 inches overall length, the stub-style screw machine format provides added rigidity compared to jobber-length bits, reducing deflection in short-hole drilling applications. Licensed machinists, tool-and-die technicians, HVAC fabricators, and maintenance mechanics are the typical users.

This drill bit is suited for use in drill presses, CNC machines, and handheld drilling equipment where a 3/4-inch hole is required. The screw machine length format is preferred in applications where rigidity and precision matter more than extended reach. General-purpose grade construction makes it appropriate for a wide range of materials including mild steel, aluminum, plastics, and composite substrates in both shop and field settings.

Key Features

• High-speed steel construction with oxide coating for improved wear and corrosion resistance
• 118-degree standard point angle for general-purpose drilling across multiple materials
• Screw machine (stub) length at 5 inches OAL for increased rigidity and reduced deflection
• Straight cylindrical shank compatible with standard drill chucks and collet holders
• Right-hand cut, 2-flute spiral design promotes efficient chip evacuation
• Conforms to ANSI specification standards

Compatibility

Designed as a general-purpose screw machine length drill bit for use in drill presses, lathes, CNC equipment, and handheld drills accepting a 3/4-inch straight cylindrical shank.

Installation Notes

Install and remove this bit only when the drilling equipment is fully powered down and secured. Ensure the chuck or collet is properly tightened before operation to prevent slippage. Use appropriate cutting fluid or coolant when drilling metals to extend bit life, noting this bit does not support through-coolant delivery. Wear appropriate PPE including eye protection when operating any drilling equipment.
