SPKN Milling Inserts

Square Insert

Insert Grade QP40
(P40) Uncoated. For rough medium and finish milling of tough Steels and Stainless Steels including interrupted cutting.

TCGT turning inserts feature a CVD coated substrate providing an excellent general purpose grade for medium roughing on steels, stainless and cast irons.

Features and Benefits
• CVD MT-TiCN-Al2O3-TiN coating for increased heat and wear resistance
• Tough substrate for increased cutting strength
• Versatile usage can be used in a range of applications from roughing to finishing
• PF chipbreaker for good chip flow

Typical Applications
• General purpose
• Medium roughing
• Finishing
• Steel
• Stainless steel
• Cast iron
Finish.

Standards
• Insert Grade QX5020
• (ISO P10-P35 M10-M30 K10-K30)

Cylindrical-End Cutting
All sizes are nominal with a 6mm shank unless other wise stated.

Cut Numbers:

Cut 3 - Rapid Cut.
for use on softer non ferrous and plastic materials, i.e aluminium, fibreglass, plastics, hard rubber and zinc alloy,

Cut 6 - Double Cut.
Crosscut and double cut to improve control and chipbreaks. Manufactured from high grade tungsten carbide for general-purpose use.

Cut 9 - Chipbreaker
Chipbreaker fast stock removal for improved control and reduced chips for use on hard materials, i.e. steel alloy 50RC, 60RC, carbon and cast iron.

Suitable for deburring and polishing of cast iron, cast steel, carbon steel, alloy steel and stainless steel etc.
up to HRC65 hardness.

Please note:
• Work piece and tools should always be steady and well supported.
• Carbide burrs are not suitable for 'milling' large amounts of material, they are for light stock removal and high revolutions 'LOW FEED - HIGH SPEED'.
• Always ensure that at least 70% of the shank length is clamped by the collet or chuck of the tool being used.
• Always ensure that the tool is rated to the recommended operating speed of the burr.

SwissBurr hand deburring tools are a fast effective and efficient way of deburring holes, slots and edges. Swiss Burr is a totally modular system of interchangeable handles, holders and blades designed to cover all applications. A choice of HSS or carbide blades, countersinks and scrapers are available to suit your specific application. Swiss Burr blades are also interchangeable with commonly available brands including Kennedy, Noga, Ruko, Seco, Snap-Tap and Stellram.

F12 - HSS countersink for hole edges up to 12mm dia.
F20 - HSS countersink for hole edges up to 20mm dia.
F30 - HSS countersink for hole edges up to 30mm dia.
