Onsrud High Performance Routing End Mill 61-000P Square End Straight O-Flute Drill Mills

High-performance routing end mill

This Onsrud carbide end mill delivers a square end and straight O-flute geometry for routing tasks. The centre-cutting plunge point allows direct entry into the workpiece without pre-drilling. Right-hand cutting action suits standard milling machines and CNC routers. It is designed for operators who need a single-end tool for general-purpose routing.

Carbide construction for rigid setups

The solid carbide body resists deflection when held in a precision collet or hydraulic chuck. Rigid machine spindles with low run-out are required to prevent chipping. The tool frees the programmer from separate drilling and profiling passes by combining both in one cutter. It is not suited for hand-held routers or low-rigidity benchtop machines lacking spindle stiffness.

Single tool reduces change-overs

The integrated plunge point eliminates the need for a separate centre drill, cutting tool-change time on CNC jobs. No coatings or additional accessories are included in the package. California Proposition 65 warning applies due to regulated chemical content. Buyers needing coated variants or multi-flute roughers must select a different product.
