fraisa.com 324 MGX HM MGD2 HM HSS Legend to the product page of drilling tools Tool technologies Drilling tools with four chamfers (Two friction and two guide lands) • Improved straightness of the hole • Improved hole quality and alignment • Less deviation of the hole when drilling through cross holes • Precise holes with good surface and maximum support of the tool upon exit Drilling tool with optimised polished flutes and internal cooling • Reduction of friction and therefore less adhesion, improved chip formation and lower heat generation Drilling tool with optimised polished flutes, without internal cooling • Reduction of friction and therefore less adhesion, improved chip formation and lower heat generation Drilling tool with shank of h5 tolerance • High concentricity and roundness • Optimal for modern precision chucks Cutting tool substrate material Fine grain carbide. Hardness 1950 HV. Co content 8%. Characterised by a particularly high level of abrasion resistance. High-performance fine grain carbide with ultrafine tungsten carbides. Hardness 1610 HV. Co content 10%. Fine grain carbide. Hardness 1600 HV. Co content 10%. Fine grain carbide with high bending and shear strength combined with good elasticity. Universal fine grain carbide. High-performance substrate material, conventionally melted HSS alloy. Tool with special edge conditioning • Conditioning of the main cutting edge for increased stability • Increase the mechanical and thermal load on the cutting edge • General increase in the tool life
