Sgs 56023 Straight-flute Drill Bit Wire Size 23 Carbide

Product Description

The SGS 56023 is a straight-flute solid carbide drill bit designed for high-performance drilling in ferrous and hardened materials. Built to DIN 6539 standards, it carries a 140-degree standard point angle with web thinning to reduce thrust and improve chip evacuation. The micrograin carbide construction provides the edge retention and rigidity needed for cast iron, hardened steel, and general steel applications. At 0.1540 inches in diameter (Wire Size 23) with a 1-inch flute length and an overall length of 2.0625 inches, this bit is sized for precision work in tight-clearance drilling scenarios. It ships uncoated and is intended for right-hand cutting operation.

This drill bit is suited for machining and fabrication environments where hardened or abrasive workpiece materials demand a carbide tool. Typical applications include toolroom work, production drilling in steel and cast iron components, and secondary operations on hardened materials. The straight-flute geometry makes it particularly effective in materials that produce short, brittle chips rather than long stringy ones, reducing the risk of flute clogging. It is installed and used by machinists, tool-and-die technicians, and maintenance professionals working on CNC machines, drill presses, or manual mills.

Key Features

• Solid micrograin carbide construction for durability in hard and abrasive materials
• 140-degree standard point angle minimizes walking and reduces thrust on entry
• Web-thinned geometry improves chip evacuation and lowers cutting force
• Straight-flute design optimized for cast iron, hardened steel, and short-chipping materials
• Right-hand cutting direction, uncoated bright finish
• Conforms to DIN 6539 dimensional standard

Compatibility

Designed as an OEM-specification solid carbide straight-flute drill bit for use in standard drill press chucks, CNC machining center toolholders, and collet systems accepting a 0.1540-inch shank diameter. Compatible with primary workpiece materials including cast iron, hardened steel, and steel, as well as secondary hardened materials per supplier specification.

Installation Notes

Installation and use of this drill bit should be performed by qualified machinists or maintenance technicians familiar with carbide tooling. Ensure the machine spindle is fully stopped and the tool is secured in a properly sized collet or chuck before beginning operations. Carbide is brittle compared to high-speed steel — avoid side loading, interrupted cuts at high feed rates, or dropping the bit on hard surfaces. Always confirm spindle speed and feed rate are appropriate for the workpiece material and bit diameter before engaging the cut.
