Carbide drilling with TSC deep holes
haas pumps limit the flow based on volume it is moving. bigger drill means bigger hole which means it takes less psi to move the volume its programed to pump which i want to say is like 7 gallons a minute. so .343 drill psi is like 600psi but a .250 drill would be like 800-900psi, well why cant...- Stove

Carbide drilling with TSC deep holes
we were told by the sales rep we can peck with these drills and have been pecking with them for 6 months. never broken a drill during pecking and chips look the same as if i wasnt pecking.- Stove

Carbide drilling with TSC deep holes
coolant pressure is limited by haas pump programing which we are looking to see if we can unlock. otherwise we have gotten similar tool life around that 40-45ft before replacing drills. but thats only if drills make it that long before chipping.- Stove

Carbide drilling with TSC deep holes
Drill never leaves the hole when peaking just comes up to where it starts in the pilot hole. When there is a cross hole chips are pushed out from the tsc so everything is clear and sounds good like no chips are being caught. Have tried drilling all the way only to e stop the machine because the...- Stove

Carbide drilling with TSC deep holes
Using a short pilot drill to start the hole that is same size as the drill we are gonna use for the hole. Pilots are nice and leave a machines like finish on the walls so don’t see that being an issue. Anything past 6in we are peaking. Manufacturer said the drills are capable of it and is...- Stove

Carbide drilling with TSC deep holes
Redline collet holders, tsc pressure seems consistent through out the cycle. but would be nice if the pump wasnt regulated as much so we could have more pressure on the deep holes, example would be the 7/16 drill has a max psi of 550 based on how that pump is programmed- Stove

Carbide drilling with TSC deep holes
I've had 2 break in the plate while drilling a normal hole, no cross hole, just drilling 6in and made it about 4in into it and snapped in half... nothing left of them after having to hammer them out with a chisel. Other drills have chipped right at the center point of the drill like when it...- Stove

Carbide drilling with TSC deep holes
What would you consider as excellent tool life? I've had a 7/16 drill 8in long drill about 40ft before sending to resharpen. I've also had that same drill chip after 10inches of drilling... am open to new drill suggestions and will have to look into Kennametal.- Stove

Carbide drilling with TSC deep holes
Currently running MITS MVS carbide drills with TSC 1000psi pump on haas vf6ss and having issues with tool life and drills breaking. Drills are being used to drill waterlines in mold bases (typically p-20 material) so depth ranges from 2in to 12in, F&S example for a .343 DIA is 19.5 @ 2200 RPM...- Stove
