GT HPC Reamers for superior performance for sizes above Ø 40,0 For sizes above 40,0 Guhring

A variety of solutions guarantee the highest cutting parameters and hole quality.

offering quick delivery times within diameter range >40,1 76,2.

stainless steels, GGG60, GG, special alloys and nonferrous material Carbide-tipped with nano-si

for aluminum machining Cermet-tipped for steels and GGG40/50 Optimized Cooling Thanks to the

cutting edges are lubricated optimally. Blockage of the coolant exits is not possible.

10 GT HPC Reamers for superior performance for sizes above Ø 40,0 For sizes above 40,0 Guhring Technology shows superior performance in reaming applications. A variety of solutions guarantee the highest cutting parameters and hole quality. Variety for perfect results GT reamer heads are available in a semi-standard product range offering quick delivery times within diameter range >40,1 76,2. GT are available in the following configurations: Carbide-tipped with nano-a coating for stainless steels, GGG60, GG, special alloys and nonferrous material Carbide-tipped with nano-si coating for GG/GGG when high-class surface finish is required Carbide-tipped with Carbo coating for aluminum machining Cermet-tipped for steels and GGG40/50 Optimized Cooling Thanks to the newly developed coolant distribution screw (patent pending) at the face of the reamer all cutting edges are lubricated optimally. Blockage of the coolant exits is not possible. Due to the flat-head coolant screw construction, blind holes can be machined to the bottom of the hole. Additionally, the coolant distribution screw can be remove if required for blind hole machining. 10
