Value Collection SC0400108 Hss Core Drill 1-1/8 in 4 Flute

Product Description

The VALUE COLLECTION SC0400108 is a high-speed steel straight core drill designed for precision hole-making in metal and other machinable materials. With a 1-1/8 inch cutting diameter and four flutes, this drill bit delivers efficient chip evacuation and smooth bore quality in a single pass. The overall length of 11-3/4 inches and a 7-1/8 inch flute length provide reach into deeper workpieces without sacrificing rigidity. An oxide coating helps reduce friction and extend tool life in moderate-duty drilling applications. The straight shank is compatible with standard drill chucks and spindles used in machining and fabrication environments.

This core drill is suited for machine shops, fabrication facilities, and maintenance operations that require accurate, clean-bore drilling in ferrous and non-ferrous materials. The right-hand cutting direction and right-hand spiral match conventional drill press and CNC spindle rotation. The 118-degree included angle is a general-purpose geometry that performs across a broad range of workpiece materials. It is typically installed and operated by machinists, tool-and-die professionals, and skilled maintenance technicians.

Key Features

• 1-1/8 inch (1.1250 inch decimal) cutting diameter for precise hole sizing
• High-speed steel construction provides toughness and heat resistance during drilling
• Four-flute design promotes chip clearance and improves bore finish
• 11-3/4 inch overall length with 7-1/8 inch flute length for extended reach
• Oxide coating reduces friction and surface wear on cutting edges
• 118-degree included angle offers general-purpose cutting geometry

Compatibility

Designed as a general-purpose straight-shank core drill compatible with standard drill press chucks, milling machine spindles, and CNC toolholders accepting straight-shank tooling in the 1-1/8 inch diameter range.

Installation Notes

Installation and operation should be performed by qualified machinists or maintenance technicians familiar with drill press or CNC equipment. Secure the straight shank firmly in a properly sized chuck or collet before operation, and verify that the spindle speed is set appropriately for the workpiece material and drill diameter. Always power down and lock out the machine before changing tooling. Use appropriate cutting fluid to manage heat buildup and extend tool life during prolonged cuts.
