A difficult tool to grind correctly. These are expertly done to give maximum cutter strength and proper clearance as cutter tip enters bore and shank approaches barrel. By taking careful cuts and moving table back and forth, any degree of crown shape can be cut.

Et vanskelig verktøy å slipe korrekt. Disse er ekspertmessig utført for å gi maksimal skjærestyrke og riktig klaring når kuttertippen går inn i løpet og skaftet nærmer seg løpet. Ved å ta forsiktige kutt og flytte bordet frem og tilbake, kan enhver grad av kronform skjæres.

real timesaver(10.10.2009)
This bit is a real time saving tool. Far superior to anything that i can grind in my own shop. And does a really solid job, double sided so you get many well cut crowns from one well ground bit.
Not as shown(17.09.2012)
Mine was only ground on one side. One of the selling points was two sided grind. Would have never ordered if I had known that but since I have it I will use it.
Not Ready to Use(21.04.2017)
When I spend this much on a bit I expect it to come ready to use out of the box. As it comes you need to grind away part of the tool as it scraps the side of the barrel before the cutting part does. Maybe if your doing .50 this would work without modification but for smaller calibers it does not.
Might as well save money and buy a blank lathe bit and grind your own.
