Sgs 56111 Straight Flute Carbide Drill Bit 11/64 in

Product Description

The SGS 56111 is a straight-flute carbide drill bit designed for precision drilling in ferrous and hardened materials. Built from micrograin carbide with a bright, uncoated finish, this bit delivers consistent performance in demanding shop and field applications. It measures 0.1719 inches in diameter (11/64 inch nominal) with a 140-degree standard point angle and a web-thinned tip geometry that reduces entry thrust. With an overall length of 2.125 inches and a flute length of 1.0625 inches, it is well-suited for short-hole drilling where rigidity and accuracy matter. The right-hand cutting direction and two-flute configuration support effective chip evacuation in ferrous materials.

The SGS 56111 is intended for drilling cast iron, steel, and hardened steel, as well as other hardened materials that demand a carbide substrate over high-speed steel. It fits standard drill chucks accepting a 0.1719-inch shank diameter and is appropriate for use in CNC machining centers, drill presses, and hand-held precision drilling equipment. Machinists, tool-and-die professionals, and maintenance technicians working with hardened workpieces will find this bit applicable to production and repair operations alike. It conforms to DIN 6539 standards.

Key Features

• Micrograin carbide construction for durability in hardened and ferrous materials
• 140-degree standard point angle with web-thinned tip for reduced entry thrust
• Bright, uncoated finish with no coating to interfere with tight-tolerance applications
• Diameter tolerance of +0.0000 to -0.0005 inches for precise hole sizing
• Right-hand cutting, two-flute straight design for effective chip clearance
• Conforms to DIN 6539 standard for straight-flute carbide drills

Compatibility

Designed for use in standard drill chucks and collets accepting a 0.1719-inch shank diameter. Suitable for drilling cast iron, steel, hardened steel, and hardened materials. Compatible with CNC machining centers and drill press setups requiring a DIN 6539 straight-flute carbide drill in the 11/64 inch size range.

Installation Notes

Installation and use of this drill bit should be performed by qualified machinists or maintenance professionals familiar with carbide tooling. Secure the shank fully in a compatible chuck or collet before operation and verify runout before drilling. Power down and de-energize all equipment before changing tooling. Carbide is brittle and should not be subjected to lateral loading or impact that could cause chipping or fracture.
