Which Annular Core Cutter Is Better?
This Is A Question In Everyone’s Mind, Which Type Of Annular Cutter To Prefer HSS Or TCT. Below Information Gives You A Brief Clarification.
HSS annular cutters are cheaper than the TCT annular cutters for smaller diameters up to 40 mm, while TCT annular cutters are cheaper than HSS for diameters above 41 mm.
Once the HSS annular cutters lose its sharpness, it can be re-ground on a grinding machine and can be used again. While re-grinding the TCT annular cutters is possible but very difficult and time-consuming.
The chances of a defect in TCT annular cutters is more because the tungsten carbide tips are glued on the annular cutters and when the annular cutters fall down or crash on the material, the chances tip breakage is more. An HSS annular cutters, on the other hand, a complete made of one material.
TCT annular cutters biggest advantage is speed and ease in which it may cut harder materials. Especially for larger diameter TCT annular cutters are very successful. While HSS annular cutters are good when drilling not very hard material and for small diameter hole sizes.
The hardness of TCT annular cutters is more than the HSS annular cutters.
We would recommend you to use HSS Standard annular cutters for your regular use, HSS Cobalt annular cutter for harder material drilling and TCT annular cutters for drilling above 40 mm diameters for all materials.
