The TYPE-NR blade shape was developed for high-speed processing of relatively soft ductile materials such as aluminum alloy, magnesium alloy, and nylon resin. By curling or shearing chips into small pieces and discharging them efficiently, it solves the conventional problem of chip clogging and enables stable, high-efficiency processing.
-
The TYPE-NH blade features a smooth R shape with tip pockets, and the large R at the blade bottom allows for smooth chip discharge.
Additionally, due to the high rigidity of the blade, it delivers excellent sharpness when machining difficult-to-machine materials such as titanium alloys and stainless steel alloys.
-
The TYPE-NT blade shape is a conventional type, allowing relatively flexible settings such as the number of blades and blade angle angles, making re-sharpening easy.
Special blade shapes such as angled blades and curved blades are manufactured based on this TYPE-NT.
-
TYPE-NTS/NRS/NHS features a unique precision release machining of the blade shape. It prevents welding and seizing of workpiece materials on the blade sides, enabling stable quality processing.
-
TYPE-NTA is the first carbide solid metal saw to feature a distinctive clam blade shape.
Even in deep groove machining, it does not get stuck in the cutting workpiece and has minimal side wear, which reduces heat generation and enables high-precision machining.

SHARP SAW Side Profile
Straight Type
Suitable for shallow groove processing and cutting small workpieces. It has high thickness accuracy, and even after re-polishing, the thickness hardly changes.
Back Taper Type
This is the typical shape of a metal saw. The amount of back taper can be customized according to the user’s processing conditions (groove depth, cutting width, processing material, etc.).
Boss Back Taper Type
It is suitable for using multiple metal saws in combination when a back taper is needed. The amount of back taper and the diameter of the boss can be customized according to machining conditions (groove depth, cutting width, processing material, etc.).
SHARP SAW-S is fully custom-made for each user, covering everything from carbide material types to blade shapes, sizes, and tolerances, delivering optimal performance for each user’s processing. Please inform our sales team of your requests regarding workpiece material and depth of processing.
We would like to propose the SHARP SAW-S carbide solid metal saw, designed with dedicated specifications.
We also accept special blades such as staggered blades, angled blades, and R blades.
