The production process of a is also quite mature, and even non standardized products can be produced in a short time.
Brad point drill bits are used for blind hole, and V boring bits are used for through hole. You can choose the type by which kind of holes you need.
V-boring bits have many different design for different board . You can tell us your requires and we will give you solutions.
In addition to the conventional dimensions in the table, the drill bit diameter within 3-15mm and the shank diameter of 8-12.7mm can be customized.
That coating reduces the friction between the chip and the body inside the flute and it helps to clear the chips out of the hole during the drilling creating cooler drilling area, no burning and longer lasting bit cutting edge.
ZY drill bits main work for MDFãchipboard and any other wood types. Because of low prices, ZY drill bits also know as Economical drill bit.
Brad point drill bits used for blind hole. If you want perfect boring hole, you could choose woodworking boring bits.
ZY is well received with low prices. And because of our excellent technology, ZY drill can meet the needs of most customers.
Also we accept customization for ZY step drill bits.
There are also many new shapes and designs on ZY drill bits. Please consult our staff for details, or tell them your special needs for punching to find a solution.
