Sgs 63169 Screw Machine Drill Bit 5.25mm Carbide Altin

Product Description

The SGS 63169 is a screw machine length drill bit engineered for high-performance drilling in demanding materials including alloy steels and titanium. Built from solid carbide and coated with an AlTiN (Ti-NAMITE-A) finish, this bit handles elevated cutting temperatures and abrasive workpieces that would rapidly degrade high-speed steel tooling. It features a 145-degree notched split point for reduced thrust and accurate self-centering, a right-hand cut, and a regular spiral flute configuration. The straight shank measures 6.00 mm in diameter. This bit is sized at 5.25 mm (0.2067 inches) and is designed for use on CNC machining centers, drill presses, and manual lathes by machinists and tooling specialists.

The SGS 63169 is well suited for production and job-shop environments where short-length rigidity matters. The screw machine length body reduces overhang and deflection compared to jobber-length bits, making it the preferred choice for through-hole and blind-hole drilling in tight fixturing setups. Primary workpiece materials listed include alloy steels and titanium. The Series 135M design incorporates a web-thinned, tapered web configuration that lowers cutting force at entry. Maximum drilling depth is rated at 20.00 mm with a flute-to-diameter ratio of 3xD.

Key Features

• Solid carbide construction for superior hardness and heat resistance in alloy and titanium drilling
• AlTiN coating (Ti-NAMITE-A proprietary finish) extends tool life in high-temperature cutting applications
• 145-degree notched split point reduces entry thrust and improves hole location accuracy
• Web-thinned tapered web lowers cutting force and chip evacuation resistance
• Screw machine length body increases rigidity and reduces deflection in short-reach setups
• Right-hand cut with 2-flute regular spiral and 2 margins for consistent hole finish

Compatibility

Designed for use in standard straight-shank drill chucks and collet holders accepting a 6.00 mm shank. Suitable for CNC machining centers, drill presses, and manual machine tool setups targeting alloy steel and titanium workpieces. No specific machine model compatibility was stated by the manufacturer.

Installation Notes

Installation and tool changes must be performed with the machine powered down and in a locked-out state per applicable shop safety procedures. Ensure the collet or chuck is rated for the 6.00 mm straight shank diameter and that runout is within acceptable tolerance before cutting. Coolant-through is not supported on this bit, so external coolant or cutting fluid should be directed at the cutting zone to manage heat when drilling titanium or hardened alloy. Inspect the cutting edges and AlTiN coating for wear or chipping before each use, as carbide tooling can fail without visible warning when pushed beyond rated depth or feed.
