Sgs 56443 Solid Carbide Jobber Drill Bit 13/64 in 135 Deg

Product Description

The SGS 56443 is a solid carbide jobber-length drill bit designed for high-performance drilling in demanding shop and field applications. It carries a 13/64 inch (0.2031 inch) diameter and a 135-degree split-point angle, which reduces walking on entry and lowers thrust requirements. The Ti-NAMITE-X (TX) coating improves surface hardness and heat resistance for extended tool life. Manufactured to DIN 6537 specification from micrograin carbide, this bit delivers consistent performance in ferrous and non-ferrous materials. It is suited for machinists, tool-and-die shops, and fabrication professionals who require tight-tolerance holes without a center punch.

The SGS 56443 is used in CNC machining centers, drill presses, and manual machines where a straight-shank, right-hand-cut bit is required. The 5xD flute-to-diameter ratio and coolant-through design make it well suited for deeper holes and applications where chip evacuation and heat management are critical. It is appropriate for production environments and precision repair work where hole diameter tolerance must be held consistently.

Key Features

• Solid micrograin carbide construction for high rigidity and wear resistance
• Ti-NAMITE-X (TX) proprietary coating for enhanced heat and abrasion resistance
• 135-degree split point reduces entry walking and decreases axial thrust
• Coolant-through design supports chip evacuation in deeper drilling applications
• Web-thinned geometry reduces cutting force at the center of the bit
• Manufactured to DIN 6537 specification for dimensional consistency

Compatibility

Designed as a standard straight-shank jobber-length drill bit compatible with any drill press, CNC machining center, or manual machine tool equipped with a chuck or collet accepting a 0.3900 inch shank diameter.

Installation Notes

Installation and use should be performed by a qualified machinist or tool operator familiar with carbide tooling. Ensure the machine spindle and chuck or collet are clean and properly tightened before use, as carbide is brittle and sensitive to runout. Power down the machine and confirm zero spindle movement before changing or inspecting the bit. Coolant lines should be confirmed clear and functional when using the coolant-through feature to prevent thermal shock to the carbide substrate.
