Brief introduction
BT ER COLLET CHUCK, With DIN6499 collet chuck can be straight shank cutter clamping various sizes.BT tool holder comes in a range of sizes designated as BT30, BT40, BT50, etc, and uses the same NMTB body taper as CAT, BT tooling is symmetrical about the spindle axis. This gives BT tooling greater stability and balance at high speeds. BT tool holders will accept both imperical and metric sized tools, BT tooling looks very similar and can easily be confused with CAT tooling. The difference between CAT and  BT is the flange>TYPE

Shank Arbor knowledge:
A. A variety of CNC tool knife handle, Arbor, CNC tool holders, tool holders
1. The key factors used to connect machine tools and cutting tools CNC tool system, with precision jig and gauge function is directly related to whether the proper use of the tool, the cutting has reached the desired effect lies.
2. machining centers with 7:24 taper shank system, including BT, SK, CAT, DIN and other standards, NT in the early CNC milling machine is used more
 
Second Arbor:
1.ER Straight extended collet shank, long shank body for deep hole machining.
2. You can reduce the use of longer tools, which can reduce costs and improve efficiency.
3. The extension rod diameter, and other parts have been precision ground to eliminate unbalance, increase stability during cutting.
