## Description

The Dormer P511 Ball Nosed Tree Carbide Burr is a precision rotary burr designed for demanding machining applications in high-temperature alloys and superalloys. This solid carbide burr features a distinctive ball-nosed tree (F shape) profile, making it ideal for multi-angle contouring, edge rounding, and accessing confined or awkward areas where conventional tools cannot reach. Manufactured from micrograin carbide, this burr delivers exceptional hardness and wear resistance when working with difficult materials. The AS single-cut flute style incorporates a light left-hand cross-cut pattern, specifically optimised for superalloy applications where surface finish quality is paramount. This cutting geometry ensures smooth, controlled material removal whilst minimising chatter and tool deflection. The ground bright finish prevents work material from adhering to the cutting edges, reducing heat generation and friction during operation. This extends tool life and maintains cutting efficiency even during prolonged use. Professional machinists and fabricators working with aerospace-grade alloys, stainless steel, and other challenging materials will find this burr particularly effective for die-sinking, deburring, and precision shaping tasks. Features and Benefits: &bull; Micrograin carbide construction provides extreme hardness and wear resistance for extended tool life when machining difficult materials &bull; Ground finish prevents work material from sticking to the cutting edges &bull; AS cut geometry ensures high quality surface finish with fast and smooth cutting action, ideal for superalloys &bull; Ball-nosed tree shape enables access to hard-to-reach areas and multi-angle contouring work Specifications: Diameter Cut: 3mm Length Cut: 14mm Shank Diameter: 3mm Overall Length: 38mm Burr Type Code: Superalloy Cut Geometry Material Code: Solid Carbide Coating: Bright Burr Shape: F - Ball Nosed Tree Shape Material Application Priority Usage: S - High-temperature alloys
