    I would love to see how a solid carbide saw would do compared to the indexable. Staggerred tooth with a Tialn coating. 64 or 48 teeth.
    Sure the cutter is more expensive. But if it lasts 2-3 times...

    Hard to say. Blank is more money. Carbide isn't cheap. Need to spin down the cutting diameter area. Every situation is different.

    This is a great point that many people overlook or forget. CNC tool and cutter grinders don't have some special magical collet system that have zero runout. Some of the newer machines actually probe...

    Yes we are working with our material supplier and our heat treater. Don't want to say yet what alloy it is but it is over 230,000 psi tensile strength and great shock resistance. It will be heat...

    +1 on the NPT and NPTF taps. They use up a lot of torque. 1/8 and 1/4 not so much. But 3/8 and up wouldn't be a bad idea to use a tap collet.

    Save your money. You dont need them ( in most cases).
    They are oversold by people trying to make a buck. A 8-32 tap collet is a joke. A standard round ER collet no matter what series is more than...

    Yes we use Diagrind for a lot of our setups. In fact I just ordered from them a few days ago. In many setups we still prefer ceramics. Easy to dress and once you dress it it is dead true and dead...

    "grinded" ;-) I saw that too.
    I think the red arrow indicated the direction of spindle rotation while grinding. Fischer is known for some really high-end spindles for grinding and machining so...

    I doubt. With sub 10 people you can be the most profitable. Once you have lets say 20 or more you need more management, human resources, accounting, payroll, billing etc. 2-3 man shops dont need any...

    Nah,
    I dont see any manufacturers doing that. Shink holders are great but they also have a lot of drawbacks as well. Bad harmonics, long gage lengths. Not one type of holder exists that you can say...
