Value Collection 1057878 Taper Length Drill 1.25in Hss-e

Product Description

The VALUE COLLECTION 1057878 is a taper length drill bit engineered for demanding material removal in industrial and trade applications. Ground from M35-grade HSS-E cobalt steel, it handles tough ferrous metals, stainless steel, and hardened alloys that standard high-speed steel bits cannot reliably cut. The bit measures 1.25 inches in diameter with a 118-degree point angle suited for general-purpose drilling. With an overall length of 12.5 inches and a flute length of 8.5 inches, the taper length profile provides extended reach beyond what a jobber-length bit delivers, making it well-suited for deep-hole work in structural and fabrication settings.

This drill bit is used in machine shop, fabrication, HVAC rough-in, and heavy mechanical trade applications where large-diameter, deep holes are required. The bright uncoated finish is compatible with cutting oils and water-soluble coolants. It is commonly driven by floor-standing drill presses, radial arm drills, or milling machines using appropriate chuck or Morse taper adapters sized for a 1.25-inch shank. Licensed machinists, ironworkers, pipefitters, and industrial maintenance technicians are the typical end users.

Key Features

• M35-grade HSS-E cobalt construction for heat and wear resistance in hard-metal drilling
• 118-degree point angle for general-purpose use across a range of ferrous and non-ferrous materials
• Taper length geometry at 12.5 inches overall provides extended reach versus standard jobber-length bits
• 8.5-inch flute length allows deep-hole chip evacuation with standard coolant or cutting oil
• Bright uncoated finish is ready for immediate use and compatible with most cutting fluids
• 1.25-inch shank diameter matches the 1.25-inch drill diameter for direct chuck or adapter mounting

Compatibility

Designed as a general-purpose taper length drill bit for use in floor-standing drill presses, radial arm drills, and milling machine setups that accept a 1.25-inch round shank or appropriately sized Morse taper adapter.

Installation Notes

Installation and operation of large-diameter drill bits of this size should be performed by qualified machinists or trade professionals using properly rated machinery. Secure the shank firmly in the chuck or taper adapter before operation and verify that the spindle speed is appropriate for the workpiece material and bit diameter. Always apply cutting fluid or oil during drilling to extend bit life and manage heat buildup. Secure the workpiece with clamps or a vise before starting the cut.
