Sgs 56017 Straight-flute Drill Bit Wire 17 Carbide

Product Description

The SGS 56017 is a straight-flute drill bit designed for precision drilling in ferrous metals, hardened steels, and cast iron. Built from solid micrograin carbide with a bright, uncoated finish, it delivers tight dimensional accuracy with a diameter tolerance of +0.0000 to -0.0005 inches. The 140-degree point geometry reduces thrust and improves centering on entry, while web thinning lowers cutting resistance at the tip. At 2.1875 inches overall length with a 1.125-inch flute, this is a compact, rigid tool suited for controlled drilling in tough materials. Cutting direction is right hand with two flutes. Manufactured to DIN 6539 standards.

The SGS 56017 is used in metalworking applications where close-tolerance holes are required in cast iron, alloy steel, and hardened steel workpieces. The straight-flute design is particularly well suited for drilling brittle materials such as cast iron, where it prevents chip packing and reduces the risk of workpiece cracking. Typical applications include production machining, tool and die work, and maintenance repair operations where a wire gauge Number 17 hole diameter of 0.1730 inches is specified. This bit belongs to SGS Series 106.

Key Features

• Solid micrograin carbide construction for wear resistance in hardened and abrasive materials
• 140-degree standard point angle for reduced thrust and accurate self-centering
• Web-thinned tip reduces cutting force and heat at entry
• Straight-flute geometry optimized for drilling brittle materials including cast iron
• Diameter tolerance of +0.0000 to -0.0005 inches for close-fit hole requirements
• Conforms to DIN 6539 dimensional standard

Compatibility

Designed for use in standard drill chucks and machining center spindles accepting a 0.1730-inch shank diameter. Suitable for drilling cast iron, steel, hardened steel, and other hardened materials where a wire size Number 17 diameter is specified.

Installation Notes

Installation and use of carbide drill bits should be performed by qualified machinists or tool and die technicians familiar with speeds, feeds, and chip control for carbide tooling. Ensure the spindle and chuck are clean and concentric before seating the bit to avoid runout that can chip carbide. Always power down and lock out the machine before changing tooling. Do not use this bit in hand-held drill applications; it is intended for rigid machine setups only.
