Sgs 56053 Straight-flute Drill Bit Wire 53 Carbide

Product Description

The SGS 56053 is a straight-flute drill bit sized at wire gauge number 53 (0.0595 inches decimal diameter), manufactured from solid micrograin carbide and left uncoated for maximum dimensional accuracy. It features a 140-degree standard point angle with web thinning to reduce thrust and improve chip evacuation at entry. The two-flute, right-hand cutting geometry is built to DIN 6539 standards, making it a precision tool suited for machinists, tool-and-die makers, and CNC operators who need consistent hole quality in ferrous materials. Overall length is 1.5 inches with a 0.5-inch flute length.

This bit is intended for drilling cast iron, steel, and hardened steel in production and job-shop environments. The micrograin carbide substrate handles the elevated hardness and abrasion of these materials where high-speed steel tooling loses edge life prematurely. Typical applications include through-hole drilling in fixture plates, die components, and hardened workpieces where hole location tolerance is tight. Maximum recommended drilling depth is 0.406 inches. It is sold and packaged as a single unit.

Key Features

• Solid micrograin carbide construction for extended edge life in ferrous and hardened materials
• 140-degree point angle reduces thrust and improves centering on entry
• Web-thinned geometry aids chip evacuation and lowers cutting force
• Uncoated bright finish maintains precise diameter tolerance of +0.0000 to -0.0005 inches
• Conforms to DIN 6539 standard for straight-flute carbide drills
• Right-hand cutting, two-flute design compatible with standard CNC and manual drill setups

Compatibility

Designed for use in cast iron, steel, and hardened steel workpieces. Primary workpiece materials listed by the manufacturer are cast iron, hardened steel, and steel, with secondary suitability for hardened materials generally. Shank diameter is 0.0595 inches, fitting collets and chucks sized for number 53 wire gauge tooling.

Installation Notes

Installation and use of this drill bit should be performed by a qualified machinist or CNC operator familiar with small-diameter carbide tooling. Secure the shank fully in a precision collet or drill chuck rated for the 0.0595-inch shank diameter before operation. Carbide is brittle — avoid side-loading or impact; use appropriate feed and speed parameters for the workpiece material to prevent breakage. Inspect the cutting edge before each use and do not run a chipped or cracked bit.
