Features and operating conditions of the tool |
Purpose |
Р18 |
High wear resistance, retains cutting properties when heated during operation up to 600°C |
Cutters, drills, milling cutters, chisels, reamers, countersinks, taps, broaches |
Р9 |
Works when cutting edge is heated up to 600 °C, it does not need much grinding and sharpening. The methods of hot plastic deformation and induction hardening are possible. |
Cutters, drills, milling cutters, saws, hacksaws, shear blades, woodworking tools |
Р12 |
Works when the cutting edge is heated up to 600 °C, a considerable amount of grinding is possible. Hot plastic deformation can be applied |
Cutters, drills, milling cutters, chisels, reamers, taps, broaches, dies, punches |
R6M5 |
Heats up to 580−600°C, with high feeds under the conditions of high mechanical and shock loads. It is possible to apply hot plastic deformation methods. |
Cutters, hobbing cutters, drills, broaches, machine taps, punches, dies, bearings. |
R18F2 |
Tools with slightly higher productivity and wear resistance in comparison with the steel P9 and P18 for machining of medium-hard materials, stainless and heat-resistant alloys. |
Working parts of cold extrusion dies, shear baler knives. |
R9F5 |
Tools with higher wear resistance for finishing operations with low feed when machining high-hardness steels, heat-resistant alloys, plastic materials, fibre, ebonite. Very bad grindability. |
Reamers, reamers. |
R14F4 |
The tool with increased wear resistance for working of very hard materials and heat-resistant alloys and plastics with hard inclusions. Very poorly grindable |
Cutters, milling cutters, worm chisels, saw segments. |
Р9К5
Р9К10 |
The tool with higher productivity, redness and hot hardness as compared with P18 steel for working of heat-resistant, titanium alloys and other hard-to-machine materials. The steel is prone to decarburization |
Chisels, hobbing and plain milling cutters, insert knives, special drills, punches and dies for cold close-forming dies. |
Р10К5Ф5
Р18К5Ф2. |
Tools with increased productivity, redness and wear resistance for working hard-to-machine materials, heat-resistant and titanium alloys. Steels do not grind well and tend to decarburize |
Cutters, hobbing cutters, knives of assembly cutters, drills, bearings. |
R18F2K8M |
Tools with higher wear resistance and durability for machining of titanium and heat-resistant alloys, stainless and high-strength steels |
Cutting tools, drills, reamers, taps, gear cutting tools. |
