Annular cutter (also called core drill or broach cutter) is high-efficient drilling cutter with Multi-edge annular cutter. The diameter of the cutter ranges from 12mm-150mm. The product is mainly used to process the drilling hole, such as steel structure project, rail traffic, bridging, shipbuilding, machine manufacture and other hole processing fields. The hole drilling performance of annular cutter is much better than the traditional twist drill , which has the characteristics of high drilling efficiency 、portable and labor-saving, thus greatly saving the labor costs . Multi-edge annular cutter is widely used in magnetic drilling machine ,drilling machine , CNC drilling machine and other machines . If it is matched with magnet drilling machine, multi-edge annular cutter is widely used in magnet drilling machine, drilling machine, CNC drilling machine and other machines, to achieve high efficiency drilling and shorten manufacturing period efficiently. The annular cutter is a very efficient tool for modern steel structural component drilling and circular groove processing. Meanwhile ,it is also a green product that energy saving and consumption reduction and in line with the development of low-carbon economy

1.Made of high performance carbide tips for better performance of hole saw.The cutting characteristics of high drilling efficiency、 portable and labor-saving makes our how saw series products become a green product under low-carbon economy
2.Diameter from 14mm to 150mm with 4,20mmD.O.C.for sheet metal and 50,75mm for pipe
3.Application to hole cutting on ceramics, vaneers

1.The control panel is designed with the combination of mechanical ship switch and micro film switch.
2.Tilt protection design for motor air Inlet avoids liquid or debris falling into the inside of the motor.
3.Double dovetail design, Adjustable spindle height can adapt to working conditions and drills.
4.Two speeds gear box with step-less speed control bring wider range of drilling;
5.Reversible with step-less speed function, applicable to the maximum size of M16 tap.
6.Motor soft start: reduce the impact on motor start and prolong the service life of the motor. DX-60X have characteristics of energy saving and consumption reduction which in line with the sustainable development of low-carbon economy .
7.Closed and guided structure of air outlet makes the front operating position and the handle side air volume reduced;
8.Rigidity design of Machine

Speed drill is a high-performance replaceable insert drill system originally launched by CHTOOLS
The triple positioning structure for which a patent is licensed features extraordinary connection strength and positioning accuracy，and the optimal geometric design and materials contribute to its excellent drilling speed and durability. Given the split replaceable construction，it can achieve flexible combination of inserts of various functions and holders of different lengths，thereby satisfying the needs of different materials t be processed，different drilling depths and other applications，and achieving the advantages of minimized tool investment and less inventory
Insert diameter range: Ø10.00-Ø39.99 mm; drilling depth: 3D，5D and 8D; insert materials include carbide and HSS-PM which match highly rigid CNC machine tools and common machine toolsrespectively. Speed drill inserts are designed to process four series of materials，i.e. steel， stainless steel，cast iron and nonferrous metals，thus meeting the needs of different materials being processed.
Compared with twist drill , the high-efficient drilling features of speed drill while greatly reduce the labor costs ,it also a green product that energy saving and consumption reduction and in line with the development of low-carbon economy 

Applicable to CNC equipment ，rocker drilling，vertical drilling，boring-milling machine，in the rail，road fork batch drilling，the using performance is excellent;
Inner cooling design of holder enable excellent chip removal and good cooling
High accuracy of the connections between the inserts and holders ensures high clamping accuracy，and easy to replace inserts
Inserts are made of powder high speed steel，combined with various coating and increase efficiency for 2 times
compare with twist drill
The design of replaceable structure can continue drilling operation without adjustment after changing the insets New cutting geometrical reduce the cutting resistance greatly
Insert have the function of chip-breaker ，which improves the stability of holes drilling.
Compared with twist drill , the high-efficient drilling features of spade drill while greatly reduce the labor costs ,it also a green product that energy saving and consumption reduction and in line with the development of low-carbon economy
