SINGLE CUT VS DOUBLE CUT CARBIDE BURR


Carbide Burrs are often recognized as rotary burrs for metal. They are widely used for cutting, shaping, grinding, removing sharp edges, burrs, and excess material (deburring). They perform the rapid removal of excess material on metals. The carbide burrs are also used in the removal of unshaped edges and on coated abrasives before finishing or polishing.

Carbide burrs are generally used for metalworking, tools manufacturing, engineering, model engineering, wood carving, jewelry making, welding, chamfering, casting, deburring, grinding, and plate port sculpting.

A Carbide rotary burr for metal is usually made either from tungsten carbide or from high strength steel (HSS). Tungsten carbide burr bits can last longer and bear higher temperatures. It will not melt, and perform effectively.


TYPES OF CARBIDE BURRS

Carbide Burrs are usually available in two cuts; Single Cut and Double Cut (Diamond Cut) burr.

Let’s understand them individually.

1. SINGLE CUT CARBIDE BURR

single cut carbide burr has a spiral flute with a right-handed (Up cut). It is ideal for cutting hard metals such as chrome steel, hard steel, copper, cast iron, and ferrous metals. By cutting the material rapidly, a single cut carbide burr can provide a smooth finish surface.

Applications of Single Cut Carbide Burr:

  • Heavy removal of fabric 

  • Milling

  • Deburring

  • Cleaning

  • Creates long chips

2. DOUBLE CUT CARBIDE BURR

double cut carbide burr is best for ferrous and non-ferrous metals, aluminum, soft steel, and for all non-metal materials like plastics and wood. Double cut burr has enough cutting edges to remove excess material quickly. 

Double cut burrs are also known as a diamond-cut burr or cross-cut burr (2 flutes cut across each other). They provide a highly smooth finish surface than a single cut carbide burr. 

Applications of Double Cut Carbide Burr:

  • Medium-light removal of fabric 

  • Deburring

  • Fine finishing

  • Cleaning

  • Smooth finish

  • Creates small chips

WHAT ARE THE DIFFERENCES BETWEEN SINGLE CUT VS. DOUBLE CUT BURR?

Following are the major differences between single cut burr and double-cut carbide burr:

  • Material Difference:  Single cut carbide burr is perfect for hard materials like iron, steel, copper, and other hard metals. Whereas double cut carbide burr is suitable for soft metals like aluminum, plastic, and wood

  • Chip Extraction: Single cut burr is not ideal for chip extraction. Double cut burr is better for chip extraction as burr have more grooves.

  • Surface Smoothness: Single cut burr provides less surface smoothness. When the metal needs high surface smoothness, double-cut diamond burr is a better choice.

  • Operation Experience: As a beginner, It is not easy to control a single cut burr while operating. Single cut burr is easy to bring“Burrs Jumping” (missing the targeting point and burr jump to another place). Whereas double cut burr is easy to control, handle, and is an ideal carbide burr tool for beginners. 

USES OF CARBIDE BURR TOOLS

These carbide burrs have wide applications in metalworking, tools designing, woodworking, jewelry making, welding, casting, deburring, grinding, porting of cylinder heads, and sculpting. Carbide burrs are also used in the aerospace, automobile, dentistry, stone, and metal industries.

Carbide burrs are best to used with power tools such as die grinders, high-speed fabricators, and hydraulic rotary tools.
