END MILLS

Solid Carbide End Mills are a wise choice for many milling applications. They are ideal on tough or abrasive materials. Carbide also has the benefit of high heat resistance. On many jobs, Solid carbide end mills, can be run faster than HSS or Cobalt End Mills, resulting in much higher productivity rates thereby lowering tool setting time / down time. Additional benefits due to the rigidity of carbide is its high precision and excellent surface finish. Carbide End Mills are successfully being used for severe metal cutting operations (High Nickel Based Alloys) which require high strength. In general the more flutes on end mills, the better the machine finish. If workpiece finish is of major importance select four or more flutes. For higher production rates fewer flutes will allow higher chip carrying capacity.

Size Range

1/8” to 1”
2 mm to 32 mm
(2 to 6 mm-in increment of 0.5 mm
6 to 12 mm-in increment of 1.0 mm
12 to 22 mm-in increment of 2.0 mm)

Square/Centre cutting & Ball Nose End Mills

Manufactured from 12% Cobalt Micro grain carbide, the Square End Mills and Ball nose end mills are suitable for finish milling of most ferrous metals at higher speed and feed rates. Depending on the number of flutes the end mills are used for roughing or finishing. Available in TiN, TiCN, TiALN and Multi layer hard coating. The range includes STANDARD LENGTH, EXTENDED LENGTH, LONG REACH, STUB (ECONOMY LENGTH), TAPER & SPECIAL END MILLS.

TWO FLUTE Geometry (suitable for plunge / slotting operations)

THREE FLUTE Geometry, A compromise between 2 & 4 flutes is used for slotting as well as profiling. This usually proves as an ideal tool for medium range materials.

FOUR FLUTE Geometry having strongest tooth forms are ideal for peripheral and profile milling operations. These are used for finish milling on harder materials.

SIX FLUTE / HI-HELIX is ideal for machining metals where high cutting forces are generated. This geometry permits higher feeds and improved tool life. This Geometry works well in most materials for finishing operations.

ALUMINIUM MACHINING

The 2 Flute Aluminium End Mills are suitable to operate at high chip loads and across a range of operating speeds. The size range from 5mm to 25mm is available in standard lengths and extended lengths.

STAINLESS STEEL MACHINING

These specially designed End Mills come in 3, 4, 5 and 6 Flute designs and in TiN, TiCN & TiALN coatings. Available in roughers with corner radius and finishers with square corners. The Helix is 45° and 50° designed for high speeds and long tool life.

TiN

Titanium Nitride (TiN) has shown good results in low carbon steels and many iron-based applications. It is a very popular coating used in the industry today.

TiCN

Titanium Carbonitride (TiCN) is a multi-layer coating. Because of the multi layer composition, the TiCN is tougher than TiN, even though TiCN is harder. The added toughness of the TiCN coating makes it a good choice for abrasive applications where higher wear resistance is required.

TiAlN

Titanium Aluminium Nitride (TiAlN) is a coating offering the ability to run even at higher temperatures. In drilling applications, this coating has produced excellent results in stainless steel, nickle-based alloys, high temperature alloys and titanium alloys. In milling, TiAlN has shown superior results in hardened steel materials. This coating has the potential to work well without coolants because of its elevated temperature resistant characteristics.

Special Ultra Thin Multilayer Hard Coating

Latest addition is the Special Ultra Thin Multilayer coating tailored to suit critical operations. This coating combines the good adhesion characteristics of TiN, Superior heat resistance of TiAlN and the ability to absorb cracking of TiCN.
