YG-1 D4148143 Screw Machine Length Drill Bit

Product Description

The YG-1 D4148143 is a screw machine length drill bit designed for precision drilling in metal, plastic, and similar materials. Screw machine length bits are shorter than jobber-length bits, which improves rigidity and reduces deflection during drilling operations. This makes the D4148143 well-suited for use in drill presses, CNC machines, turret lathes, and screw machines where stub-length tooling is required. The reduced length provides added stability when drilling at high RPM or when working in tight clearance applications.

This drill bit is used in metal fabrication shops, machine shops, and production environments where stub-length drills are standard tooling. It is also appropriate for maintenance and repair operations requiring accurate, chatter-free hole generation in confined spaces or with limited spindle travel. The D4148143 ships as a single-piece unit.

Key Features

• Screw machine (stub) length construction for improved rigidity over jobber-length bits
• Reduced length minimizes deflection and chatter during high-speed drilling
• Suitable for use in drill presses, CNC equipment, turret lathes, and screw machines
• Single-piece packaging for individual replacement or tooling replenishment
• Lightweight at 0.09 pounds

Compatibility

Designed as an OEM-style replacement or standard tooling addition for screw machines, drill presses, and CNC machining setups that accept stub-length drill bits of the corresponding diameter and shank size.

Installation Notes

Installation of this drill bit is performed by machinists and tool-and-die professionals. Secure the bit fully in the chuck or collet before operation and confirm the spindle is at a complete stop before changing tooling. Inspect the cutting edges for wear or damage prior to each use. Follow applicable shop safety standards for rotating machinery when operating powered drilling equipment.
