Kennametal Carbide Drills for Stainless Steel (Y-Tech)

Y-TECH™ Drills with Through Coolant for Difficult-to-Machine Materials

Primary Application

The B29_YPL Series Solid Carbide Drills are specifically engineered to drill stainless steel, high-temp alloys, and difficult-to-machine materials.

Y-TECH drills deliver best-in-class hole quality and longest tool life in these difficult-to-machine workpiece materials. Operate these drills with standard through coolant or MQL.

Features and Benefits

YPL Drill-Point Design

Ensures good centering and chip formation.
No jamming of chips and enables easy reconditioning.

Uneven Flute-to-Flute Angle

Unbalanced forces by design eliminate chipping on margin lands.

Three-Margin Lands

Reduce pendulum motion by directing forces towards third margin, which results in superior hole accuracy (cylindricity, constant diameter, hole straightness).

Customisation

Intermediate diameters available as semi-standards.
Length variations and step drills available as engineered solutions.
Using Kennametal Slim Line Hydraulic Chucks together with standard B29_YPL is recommended if workpiece contours need to be bypassed.
