Chicago-latrobe 50468 Extra Length Drill Bit 0.1562 in Hss

Product Description

The CHICAGO-LATROBE 50468 is a Series 120X extra length high speed steel drill bit designed for long-reach drilling applications where standard-length bits fall short. The bit measures 0.1562 inches in diameter with an overall length of 8 inches, giving technicians and machinists the reach needed to bore through deep sections, stacked materials, or confined-access workpieces. The 118-degree drill point angle and notched point type allow for clean entry into cast iron and steel. The oxide finish provides baseline lubricity and corrosion resistance. Right-hand cutting with a regular spiral and two flutes, this bit suits production and maintenance drilling in metal fabrication, mechanical, and industrial service environments.

This bit is built for long-reach drilling in cast iron and steel. The 5.5-inch flute length and 8-inch overall length make it appropriate for through-holes in thick stock, deep blind holes, or applications where standard jobber-length bits cannot reach. The straight-cylindrical shank seats in standard drill chucks without adapters. It is a general-purpose grade bit suited for use in drill presses, CNC machines, and handheld power tools across machining, maintenance, and fabrication shops.

Key Features

• Extra length at 8 inches OAL for deep-hole and long-reach drilling
• High speed steel construction for durability in cast iron and steel
• 118-degree notched point with web-thinning for reduced thrust and cleaner starts
• Oxide finish for lubricity and basic corrosion resistance
• Straight-cylindrical shank compatible with standard drill chucks
• Right-hand spiral flute for efficient chip evacuation in deep holes

Compatibility

Designed for long-reach drilling in cast iron and steel workpieces. Fits any standard drill chuck accepting a 0.1562-inch straight-cylindrical shank. Suitable for drill presses, CNC drilling machines, and variable-speed handheld power tools.

Installation Notes

Secure the shank fully in the chuck and verify runout before drilling. Use cutting fluid when drilling steel to extend tool life and improve hole finish. Ensure the workpiece is firmly clamped before starting the cut. Dispose of metal chips and worn cutting tools in accordance with applicable shop safety and California Proposition 65 handling guidelines.
