Overview: The document provides detailed specifications and guidelines for the TAF Indexable Type Drill, highlighting its features, applications, and recommended usage conditions.

Specifications: The TAF drill series includes 2D, 3D, and 4D types, with the ability to increase drill diameter in 0.1mm increments up to 0.5mm. The drills are designed for low noise and high durability, featuring four cutting edges per insert for economical use.

Features: The drills have a tough body with a wide web design to reduce chattering and ensure lower cutting noise. High insert seat rigidity ensures reliable insert location. The VP15TF (U2 breaker) is introduced for stable machining across a wider application area.

Grade and Material Compatibility: The drills are compatible with various materials including carbon steel, alloy steel, stainless steel, cast iron, and ductile cast iron. Different grades and breakers are recommended based on the material type.

Cutting Performance: The document includes performance data comparing cutting power, torque, and thrust against competitors, with specific conditions such as workpiece material and cutting speed.

Applications: The TAF drills are suitable for angled face drilling, round workpiece drilling, and open-sided drilling. They are not recommended for stack drilling due to the production of a round disc on exit.

Recommendations: For optimal performance, ensure high rigidity in machine setup and workholding. Coolant pressure and volume are critical for efficient use. When drilling oversized holes, the offset should not exceed 2% of the diameter.

JUST FIT SLEEVE: This accessory allows for incremental increases in cutting diameter, enhancing the versatility of the TAF drills. The sleeve should be aligned properly during installation, and fine adjustments are not possible.

Ordering Information: The document provides guidelines for ordering the JUST FIT SLEEVE, either as a set or individually, with specific order numbers provided.
