Code system

Features
■ Optimally designed chip pocket
Wide and deep chip pocket improve chip control to minimizing friction
during an operation
■ A curvilinear edge
A curvilinear edge offers excellent wear resistance and shock resistance
by dispersing the cutting load
■ 3D, 5D, 7D Standardization
For example) diameter Ø10mm and depth 30mm and outer coolant system,
Take MSD100-3P!
■ MSD : Solid Type & MSDH : Through oil-hole type
Various designations of MSD & MSDH enable to do any drilling
■ Low cutting resistance edge
The MSD & MSDH low cutting resistance edge guarantees a better surface
roughness andchip control while allowing the drill to center itself
■ Rigid neck of drill
The new design of this drill has an increased rigidity at neck.
This prevents breakage of neck on the drill

■ Low cutting resistance edge
Uniformity in
cutting edge treatment :
Reinforces equalized quality in every
machined part
Protecting workpiece : Low cutting resistance edge operates well in
medium to finishing machining, workpiece
protection and good surface roughness
Better chip breaking : Based on our cutting processes studies,
our drills assure better chip breaking
in high or low speeds

Note)
1. Decrease cutting speed 30%~40% contrast with recommended condition when machining forged steel
2. Decrease cutting condition considering the overhang of drill, machined rigidity, precision of spindle,
clamping and surface of workpiece, etc.
3. For longer tool life, Please apply to step feed at every 1.5D
4. Put the drill clamping between edge groove and shank boundary part in order to be located in the suitable position
5. Coolant pressure for through hole type = 3~5kg/cm3, volume = 2~5l/min
6. Cutting formula :

Note) Recommended cutting speed is one of the important factors for the drill performance. In case of using further cutting speed
or feed rate than recommended conditions to improve the productivity, please apply it after enough tests because it could be
occurred some problems like early wear, built-up edge, chipping, fracture, etc.
