4 FLUTE: Features four cutting edges (flutes). This design provides a strong core, excellent tool rigidity, and produces a highly polished surface finish. It is optimized for peripheral side milling, profiling, and light finishing slots.
14: Represents a 14 mm outer cutting diameter.
D14: Denotes a 14 mm straight cylindrical shank diameter, which ensures a direct 1:1 match with standard 14 mm tool holders or collets (such as ER25 or ER32 collets).
100L: Signifies a 100 mm overall length (OAL) from the base of the shank to the tip. This length provides extended reach compared to standard short-series bits.
HRC55: Indicates that the tool is engineered to efficiently machine workpieces with a material hardness rating up to 55 Rockwell C (HRC). It typically features a TiSiN (Titanium Silicon Nitride) coating, which gives the tool exceptional thermal resistance and high surface lubrication.
🏭 Material & Application Range
This standard tooling configuration is suitable for:
Materials: Carbon steel, alloy steel, tool steels, pre-hardened steels, and cast iron.
Operations: Side milling, 90-degree shoulder profiling, shallow slots, and finish machining.
Geometry Note: It features a standard 35-degree helix angle to balance clean chip evacuation with cutting edge stability.
