Bordo 10mm 90 Degree HSS Co5 TiN Coated Cross Hole Countersink 3850-10

10mm 90 Degree HSS Co5 TiN Coated Cross Hole CountersinkCross hole countersinks are ideal for countersinking and deburring in a wide range of materials including ferrous and non-ferrous metals.The intersection of the hole and cone form the cutting edge on the tool.The cone is not truly symmetrical as it is essential that the cone retreats away from the cutting edge as the tool rotates.If this does not occur the cutting edge will lack clearance and rub rather than bite into the material.This clearance is referred to as cutting relief.The radially relieved single cutting edge provide fast stock removal with low vibration for chatter- free operation ensuring the smoothest finish.These tools are best used as deburring tools, where a burr, or sharp edge, from a previous machining operation needs to be removed for cosmetic and safety reasons, however they may be used in softer materials (such as wood or plastic) to create a countersunk hole for a screw.Titanium Nitride (TiN) Coated Countersinks have a very hard gold coloured surface finish.This coating is only a few microns thick and is achieved by Physical Vapour Deposition (PVD).This treatment results in reduced friction, greater heat dissipation and reduced cold welding - which means higher speed and feed rates with greatly increased tool life.As with all surface coated tools, performance will deteriorate after resharpening.

Damaged / Change of Mind

Please inspect your order upon reception and contact us immediately if the item is defective, damaged or if you receive the wrong item, so that we can evaluate the issue and make it right


Certain types of items cannot be returned, like perishable goods and custom products (such as special orders or personalized items). We also do not accept returns for hazardous materials, flammable liquids, or gases. Please get in touch if you have questions or concerns about your specific item.
