Walter-titex 5537159 Screw Machine Drill Bit 0.2205 in Carbide

Product Description

The WALTER-TITEX 5537159 is a solid carbide screw machine length drill bit designed for high-performance drilling in demanding production environments. Built to Series A3289DPL specifications, this bit features a 140-degree X-treme Plus point and a double coating finish that extends tool life when cutting through abrasive and hard materials. At 0.2205 inches (5.60 mm) in diameter with a 2-flute spiral flute design and web-thinned tapered web, it delivers clean entry and efficient chip evacuation. Coolant-through capability makes it well suited for high-duty-cycle CNC applications. Licensed machinists and tool-and-die professionals specify this bit for precision hole work in ferrous and non-ferrous materials.

This drill bit is engineered for use on cast iron, hard materials, non-ferrous metals, stainless steel, and steel, making it a universal performer across production machining operations. Its screw machine length body fits standard toolholders in CNC machining centers, drill presses, and automated production equipment. The straight-cylindrical shank seats securely in collets or chucks sized for a 6.00 mm shank diameter. The 3xD flute-to-diameter ratio and maximum drilling depth of 0.7874 inches (20.00 mm) suit through-hole and blind-hole work in short-reach setups. This bit is a direct fit for shops running high-volume runs where consistent hole geometry and coating durability are critical.

Key Features

• Solid carbide construction with double coating for extended wear resistance in hard and abrasive materials
• 140-degree X-treme Plus point geometry reduces thrust and improves centering without a pilot
• Coolant-through design supports high-speed, high-cycle CNC operations
• Web-thinned tapered web lowers cutting forces and improves chip flow
• Right-hand cut, regular spiral flute configuration for standard clockwise spindle operation
• Meets DIN and ISO standards; material grade K30F carbide substrate

Compatibility

Designed as an OEM-style screw machine length drill bit compatible with primary workpiece materials including cast iron, hard material, non-ferrous metal, stainless steel, and steel. Fits collets and chucks accepting a 6.00 mm straight-cylindrical shank.

Installation Notes

Installation and tool changes should be performed by a qualified machinist with the spindle fully stopped and machine power isolated per shop lockout-tagout procedures. Verify collet or chuck runout before seating the bit, as excessive runout accelerates edge wear on carbide tooling. Confirm coolant flow paths are clear before engaging through-coolant supply. Do not exceed the rated maximum drilling depth of 0.7874 inches per pass without pecking or coolant flush to prevent chip packing.
