Sgs 56142 Straight-flute Drill Bit 5/32 in Carbide

Product Description

The SGS 56142 is a straight-flute drill bit engineered for precision drilling in ferrous and hardened materials. Built from micrograin solid carbide with an AlTiN coating, it delivers extended tool life and heat resistance in demanding production environments. The bit measures 5/32 inch (0.1563 inch decimal) in diameter with a 140-degree point angle and a web-thinned tip that reduces entry force and improves centering accuracy. Overall length is 2.0630 inches with a 1-inch flute length. Cutting direction is right-hand with a standard point type. This bit is sized and specified for machine shop, toolroom, and manufacturing applications where tight tolerances are required.

The SGS 56142 is intended for drilling cast iron, hardened steel, and steel in CNC machining centers, drill presses, and production drilling setups. Its straight-flute geometry makes it well suited for brittle materials such as cast iron, where chip control and rigidity are priorities. The 5/32 inch diameter and 3xD flute-to-diameter ratio position it for shallow, precise bores in tight-tolerance work. Series 106 designation places it within SGS standard carbide drill offerings for industrial use.

Key Features

• Micrograin solid carbide construction for rigidity and wear resistance
• AlTiN coating provides heat resistance and extends tool life in ferrous materials
• 140-degree point angle with web thinning reduces thrust and improves entry accuracy
• Straight-flute design optimized for drilling cast iron and other brittle workpiece materials
• Right-hand cutting, two-flute configuration for efficient chip evacuation
• Conforms to DIN 6539 standard

Compatibility

Designed as an OEM-style replacement or direct-fit drill bit for Series 106 straight-flute carbide drill applications in cast iron, hardened steel, and steel workpieces per DIN 6539.

Installation Notes

Installation and use should be performed by qualified machinists or tool and die professionals. Secure the shank fully in the chuck or collet before operation and verify runout is within acceptable limits. Power down and de-energize the machine spindle before changing or inspecting the bit. Do not exceed the recommended maximum drilling depth of 51/64 inch (0.8000 inch) for this bit configuration.
