Metal burrs with 3 mm shank

Carbide burrs of different shapes 

A burr is a universal tool for processing various materials: metal, steel, non-ferrous metals, cast iron, stainless steel, hardened steel, granite, ceramics, plastic, glass, tiles, porcelain stoneware, wood and other materials.

Burr design and types: 

The design of a carbide burr consists of a shank and a carbide head of a certain shape soldered to it with copper or silver. 

Types of burrs:

Burr type A – cylinder with smooth end

Burr type B – cylinder with end tooth

Burr type C – cylinder with spherical end

Burr type D – sphere

Burr type E – oval

Burr type F – rounded parabola

Burr type G – pointed parabola 

Burr type H – torch

Burr type J – taper 60*

Burr type K – taper 90 *

Burr type L – spherical conical 

Burr type M – cone

Burr type N – reverse cone 

Burr type S – truncated cone

Burr type T – T-shaped

Burr type U – concave cylinder

Burr type Y – disc 

In addition, there are several types of notches on the working part of the burr. The most universal of them is “X” - notch (cross, double notch). Single notch. Mainly used for processing non-ferrous metals (aluminium, copper, and other metals), the tool operates at lower speeds and does not stick with chips. A single cut with a large pitch is also used for processing non-ferrous metals; it removes more material in one pass. Works effectively on soft materials: plastic, wood, etc.
