Narex 8112 Mortice Chisel - 4mmNARCHIMORS-4
Narex mortice chisels are accurate, hard and immensely tough. Used for material removal as well as cutting mortice joints. The sides taper in height and length from tip to shoulder resulting in excellent cutting performance.
The blade is forged from Chrome Manganese (Cr-Mn) steel and heat treated up to 59 HRc (Rockwell Hardness Scale). The Chrome Manganese (Cr-Mn) steel used in Narex chisels is a low-alloy high-carbon steel developed specifically for making edge tools using the isothermal hardening method. This produces very strong chisels with edge taking and holding properties similar to carbon steel tools. Grind at 25 and hone at 35 degrees. Honing angles can be adjusted to suit your needs - a little steeper for greater edge durability or a little shallower for easier cutting.
The ergonomic handle is made from stained beech with a chrome steel ferrule, strong enough to withstand heavy blows from a mallet.
Chisel comes supplied with a chisel edge guard.
