Chicago-latrobe 49760 Taper Length Drill Bit 15/16 in Hss

Product Description

The CHICAGO-LATROBE 49760 is a taper length, straight-shank drill bit engineered for general-purpose drilling in ferrous metals. Built from high speed steel with a coated finish, it measures 0.9375 inches in diameter and carries a standard 118-degree split point with a web-thinned, tapered web configuration. The spiral flute runs 6.125 inches, supporting chip evacuation during deep-hole work. At 10.75 inches overall length, this bit reaches depths that jobber-length drills cannot. Right-hand cutting direction and a 0.9375-inch straight shank make it compatible with standard drill chucks and milling setups. Diameter tolerance is held to +0.0000 to -0.0012 inches for consistent hole sizing.

This bit is suited for production and maintenance drilling in alloy steel, carbon steel, and cast iron. The taper length body provides added rigidity compared to jobber bits while still allowing access to deeper features in plate stock, flanges, and structural sections. Typical users include machinists, millwrights, and maintenance technicians working on fabrication or repair operations where hole depth requirements exceed standard jobber-length capacity. The general-purpose grade and regular spiral type make it a reliable choice across a broad range of ferrous workpiece materials without requiring specialty coolant or high-pressure delivery.

Key Features

• High speed steel construction for durability across alloy steel, carbon steel, and cast iron
• 118-degree standard point with web thinning for improved penetration and reduced thrust
• Taper length body at 10.75 inches overall provides reach beyond standard jobber bits
• 6.125-inch spiral flute length promotes chip clearance in deeper holes
• Coated finish extends cutting edge life under general-purpose conditions
• Straight shank at 0.9375 inches diameter fits standard drill chucks without adapters

Compatibility

Designed as a general-purpose taper length drill bit compatible with standard drill chucks, drill presses, and milling machine setups accepting a 0.9375-inch straight shank. Suitable for drilling alloy steel, carbon steel, and cast iron workpieces.

Installation Notes

Installation and use should be performed by qualified machinists or maintenance personnel familiar with machine tool operation. Secure the shank fully in the chuck and verify runout before beginning a cut. Always power down and lock out the machine before changing bits or clearing chips. Consult applicable shop safety standards and machine manufacturer guidelines for feed rates and speeds appropriate to the workpiece material.
