The group selects superior raw materials, such as tungsten carbide alloy bars, adopts the advanced CNC processing equipment, uses the MITUT0Y0 instrument for nondestructive testing and ZOLLER fine testing equipment to detect drill diameter, drill point, cutting edge and blade belt. Also, the group is strictly following the international quality system, such as ISO9001, ISO14000, to produce high-quality products. It has a professional and efficient management system, abundant technical support and high level of integration diathesis employees. Owning the innovative technology development, steady batch production, strict inspection and sound after-sale services, the group ensures the stability of product accuracy and quality, which is comparable to At present, the company has established long-term cooperation with plenty of well-known enterprises

The screw Angle of twist drill mainly affects the size of cutting edge Angle, edge edge strength and chip removal performance, which is usually 25 32 Spiral grooves can be processed by milling, grinding, hot rolling or hot extrusion, and the front end of the drill bit forms a cutting part after grinding. The cutting Angle of the standard twist drill is 118, the bevel Angle of the cross edge is 4060, and the back Angle is 8 20. Due to structural reasons, the rake Angle is large at the outer edge and gradually decreases to the middle, and the transverse edge is negative rake Angle (up to about -55), which acts as extrusion when drilling. we are a professional manufacturer of power tool accessories, we are specilized in various cutting tools and tool set, drill bits, hole saw, cutting discs, etc. Our Twsit drill bits are exported to many countries all over the world. We produce HSS twsit drill bits for metal working, carbon steel drill bits for wood working, and also masonary drill bits for concrete works. We provide OEM if you have large quantity, custom the twist drill bits as customers' request. We can produce various sets include different size in metric and inch. and hope we can start our cooperation in the future.

PCD sintering drill bits products are suitable for different grades of aluminum alloys and CFRP/GFRP materials. And can be used in abrasive materials in the automotive, aerospace and all composite material processing industries to meet the high quality requirements for drilling. Application of PCD drilling tools -Different kind of CFRP materials -GFRP materials -Very abrasive material -High quality holes Specification CFRP is notoriously difficult to machine without delamination, uncut fibers and fiber pullout. Compared with traditional coated tools, even at higher cutting parameters, not only the process is more reliable but also the blade life is longer Using advanced PCD sintering technology to achieve a high degree of process reliability and stability The outlet of the processed hole has almost no breaks and burrs, and the surface quality of the hole wall is good; For composite materials processing, minimize the risk of delamination PCD sintering drill bits cutter body are made of fine-grained carbide material, PCD cutting edge is sharper, while bringing higher machining quality and longer tool life.
