Carbide Cutting tools benefits

Strength - Because carbide is a combination of carbon and variety of other extremely strong chemical elements, the results is material power full enough to cut through cast iron. Its torque strength is twice that of high speed steel and its compression strength is equally impressive.

Toughness - Carbide cutting tools on their own are tough, but with the added coatings available, they become almost indestructible tools for the machine industry to use in their cutting machines. Resistant to abrasions, thermal deformation and other material wear, carbide produces a quality cut and rarely needs repair or replacement.

Value - Because Carbide cutting tools work at high speeds without warping, and cut through even the toughest of materials, it keeps the assembly line working fast and productively. Its value is immense in that productions loads can be increased without extra wear and tear on parts, as well without any damage to the product being produced. Overall, this make carbide cutting tools a preference over high speed steel for machinists and other industry professionals.

Carbide Grades


Carbide hardness and toughness can be altered, dependent upon the relative quantities of Carbide and matrix metal powders in the mix prior to cementing and sintering.

The International Systems Organisation (I.S.O.) have produced codes to simplify selecting the correct grade of Carbide.

CUTTING CONDITIONS

CODE COLOUR
Finishing Steel, high cutting speeds, light feeds, Favourable conditions

P01 BLUE

Increasing wear resistance

Increasing cutting speed.

Increasing shock resistance.

Increasing feed.

Finishing & light roughing of Steel & Castings with no coolant

P10
Medium roughing of Steel, less favourable conditions. Moderate cutting speeds & feeds.

P20
General purpose turning of Steel & Castings, medium roughing.

P30
Heavy roughing of Steel & Castings, Intermittent Cutting, low cutting speeds & feeds.

P40
Difficult conditions, heavy roughing/intermittent Cutting, low cutting speeds & feeds.

P50
Finishing Stainless Steel at high cutting speeds.

M10 YELLOW
Finishing & medium roughing Alloy Steels.

M20
Light to heavy roughing Stainless Steel & Difficult to cut materials.

M30
Roughing tough skinned materials at low cutting Speeds.

M40
Finishing Plastics &Cast Iron

K01 RED
Finishing Brass & Bronze at high cutting speeds & feeds

K10
Roughing Cast-Iron, Intermittent cutting, low speeds & High feeds.

K20
Roughing & finishing Cast-Iron & non-ferrous materials. Favourable conditions.

K30
