Customized Solid Carbide End Mills Tungsten Carbide Material For High Speed Cutting
Solid Carbide NC Sporting Drill / Center drill bit
Center drills are used with the lathe to drill a hole in the end of stock for mounting between centers in the lathe.
They are designed to drill a small diameter pilot hole followed by a 60 degree countersink that provides a bearing surface for the 60 degree point of the lathe center.
Center drill are also used extensively with the milling machine to accurately start holes.
The hole locations can be dialed in using the milling machine's calibrated hand wheels, then the hole is started using the center drill.
The large diameter shank on the center drill holds the drill point right on center, once the hole is started, the center drill is replaced with a drill of the desired diameter and the hole is finished.
It is imperative hat a cutting lubricant is used, and the center drill is backed off several times to prevent the tip from twisting off.
Fixed-point drilling plays the role of fixing the location of holes. Hardware sells almost as much as central drilling. The front end is small as the drill bit, and the back end is angular as the drill bit; it has the function of positioning and chamfering.
Some are just a factory term, mainly in order to facilitate the location of drilling holes and drill small holes in advance in the location where the need for drilling holes, fixed-point drilling is usually used in the center of the drill, may also be small diameter of the bit.
Central drilling is the function of restricting the location of holes in case of drilling deviation.
Speciafication and Feature
1. Self feeding screw point provides fast boring in hard and soft woods, for precise and easy drilling.
2. Solid center design provide extre rigidity and excellent chip-carrying capacity.
3. Wide lands keep the bit straight as it bore through the hole.
4. Strict standard for consistent quality assurance.
