Value Collection 01430255 Extra Length Drill Bit Hss

Product Description

The VALUE COLLECTION 01430255 is a high-speed steel extra length drill bit designed for deep-hole drilling applications where standard-length bits cannot reach. With a 0.3906-inch diameter and a 12-inch overall length, this bit delivers extended reach without sacrificing rigidity. The 118-degree standard point angle provides a versatile cutting geometry suited to a wide range of metals and general-purpose materials. An oxide finish reduces friction and provides light corrosion resistance during service. This bit is a tool for machinists, maintenance technicians, fabricators, and mechanical contractors who require deep-hole capability in production or field environments.

This extra length drill bit is used in applications where standard 118-degree jobber bits lack the reach required. Typical scenarios include drilling through thick structural steel, deep-section aluminum extrusions, stacked material assemblies, and similar workpieces encountered in HVAC equipment fabrication, mechanical contracting, and general metalworking. The straight-cylindrical shank fits standard drill chucks on benchtop drill presses, magnetic drills, and handheld power drills. Right-hand spiral flutes evacuate chips efficiently through the 9-inch flute length during deep-hole passes.

Key Features

• High-speed steel construction for durability across a broad range of metals and general-purpose materials
• 12-inch overall length with 9-inch flute length for deep-hole drilling reach
• 118-degree standard point angle with web-thinned, tapered web for reduced thrust and easier starting
• Oxide finish reduces surface friction and provides light corrosion resistance
• Regular right-hand spiral flutes promote effective chip evacuation in deep-hole passes
• Straight-cylindrical shank fits standard three-jaw drill chucks without adapters

Compatibility

Designed as a general-purpose extra length drill bit compatible with standard three-jaw drill chucks accepting a straight-cylindrical shank at 0.3906-inch diameter.

Installation Notes

Installation and use should be performed by a qualified machinist or mechanical tradesperson familiar with drill press and rotary tool operation. Secure the workpiece firmly before drilling to prevent movement during the cut. Reduce feed pressure on breakthrough to avoid grab or bit damage. Apply cutting fluid appropriate to the workpiece material when drilling deep holes to manage heat buildup through the extended flute length.
