YG-1 D4148109 Screw Machine Length Drill Bit

Product Description

The YG-1 D4148109 is a cobalt gold plate screw machine length drill bit designed for high-performance drilling in metal and other hard materials. Screw machine length bits feature a shorter flute and overall length compared to jobber-length bits, providing greater rigidity and reduced deflection in drill press and CNC applications. The cobalt construction improves heat and wear resistance, extending tool life when cutting ferrous metals, stainless steel, and other abrasive workpieces. This bit is suited for machinists, tool and die shops, and maintenance technicians who require a compact, rigid cutting tool.

Screw machine length drill bits are commonly used in production drilling environments where a shorter bit reduces chatter and improves hole accuracy. The reduced length makes this bit well suited for drill press work, turret lathes, and screw machine operations where throat clearance is limited. It is appropriate for both shop and field use wherever a rigid, stub-length drill is required.

Key Features

• Cobalt construction with gold plate finish for improved heat and wear resistance
• Screw machine (stub) length for greater rigidity and reduced deflection
• Suitable for drilling ferrous metals, stainless steel, and hard alloys
• Compact flute length improves performance in drill press and CNC setups
• Sold as a single bit per package

Compatibility

Designed as a standard screw machine length drill bit suitable for use in drill presses, CNC machining centers, turret lathes, and screw machine operations requiring a stub-length cobalt bit.

Installation Notes

Secure the bit firmly in a drill chuck or collet before use and verify proper centering to avoid runout. Always wear appropriate eye protection and secure the workpiece before drilling. Replace or resharpen the bit when cutting performance declines to avoid overheating and workpiece damage. Consult applicable shop safety standards and machine manufacturer guidelines for proper speeds and feeds.
