EDVT Collet chuck holder

EDVT Collet chuck holder

● Product description:
1.The extension rod has a built-in top wire: it can limit the tool and adjust the length of the knife to improve the working efficiency.
2.The product handle is straight, suitable for holding small drills and milling tools; it can reduce the use of extended cutters, reduce costs and improve efficiency.
3.The parts of the product are precisely ground to eliminate the unbalance and increase the stability during cutting.
4.Straight shank ER extension rods are widely used in machining centers, milling machines, lathes, drilling machines, tapping machines, etc.

<● Features:
1.High hardness: material 20CrMnTi, surface hardness is 52-55HRC, core hardness is 40-45HRC
2.High precision: coaxiality <= 5um, ER straight shank extension rod, long handle, suitable for deep hole machining,
3.High stability: the outer diameter of the extension rod and other parts are ground to eliminate the unbalance margin and facilitate the stability of the cutting
