I have seen this function but have never used it or had a need.
Curious…
Is this for use with endmills or drill bits?
Several options for this I see. Which situation is used for each of said options?
Let’s say I want holes in MDF for endmills, can I just us the size endmill I want for said hole?
For my use of this function, I have used a smaller end mill to cut the hole. Use of a drill bit that is not made for the speed we use causes issues. Burned bits, frayed edges.
It take a bit of time to do this function. I was very pleased with the outcome.
I used it on aluminum and got a perfect hole after I tightened the belts.
I’m pilot drilling & hole milling (helical) holes in aluminum with the same bit. I’m peck drilling about 0.030 - 0.050" pecks with full retract to clear chips. Regular drill bits will NOT work on aluminum at these spindle speeds. I suppose it would work on wood OK, but then you need a lot of collets for each drill size needed.
