Walter-titex 5200221 Solid Carbide Screw Machine Drill Bit

Product Description

The WALTER-TITEX 5200221 is a solid carbide screw machine length drill bit designed for high-precision drilling in demanding production environments. The bit measures 0.125 inches (1/8 inch) in diameter with an overall length of 2.5984 inches and a flute length of 0.7874 inches. It features a 150-degree drill point angle with a Form V+A point type and web thinning for reduced thrust and cleaner entry. A straight-cylindrical shank and two spiral flutes with a tapered web configuration deliver stable chip evacuation. Coolant-through capability makes this bit well-suited for deep-hole applications where heat management is critical. Licensed machinists, tool-and-die tradespeople, and precision drilling technicians are the primary installers of this type of bit.

The 5200221 is rated for universal tool performance across a broad range of workpiece materials including cast iron, hard materials, non-ferrous metals, stainless steel, and steel. Its screw machine length profile fits short-travel applications where rigidity and runout control matter, such as CNC machining centers, drill presses, and manual production drilling fixtures. The 3xD flute-to-diameter ratio supports controlled chip evacuation in both through-hole and blind-hole configurations. The Series A6181TFT designation identifies this bit within the WALTER-TITEX product family for sourcing and replacement purposes.

Key Features

• Solid carbide construction in material grade K30F for hardness and wear resistance
• 150-degree Form V+A drill point with web thinning for reduced entry thrust
• Coolant-through design for thermal management during extended drilling cycles
• Right-hand spiral flutes with tapered web configuration for efficient chip removal
• Straight-cylindrical shank conforming to DIN 6535HA specification
• Meets DIN and ISO standards for dimensional consistency and interchangeability

Compatibility

Designed as an OEM-style replacement or production drill bit for use in standard straight-shank toolholders and collet chucks accepting a 0.125 inch diameter shank. Suitable for machine tools conforming to DIN and ISO tooling standards. Primary workpiece materials include cast iron, hard materials, non-ferrous metals, stainless steel, and steel.

Installation Notes

Installation should be performed by a qualified machinist or tooling technician. Secure the shank fully within a compatible collet, drill chuck, or toolholder before operation and verify runout before cycling. Power down and lock out the machine before changing tooling. Do not exceed the maximum drilling depth of 0.4724 inches per pass without chip-clearing cycles when coolant-through supply is not available.
