THERE ARE THREE CHARACTERISTICS THAT AFFECT THE PERFORMANCE OF ANY CUTTING MATERIAL, THEY ARE:
TOUGHNESS
— THE RELATIVE ABILITY OF THE STEEL TO WITHSTAND DEFLECTION AND INTERRUPTED CUTS WITHOUT CHIPPING.
WEAR RESISTANCE
— THE RELATIVE ABILITY OF THE STEEL TO WITHSTAND THE ABRASIVE ACTION OF DIFFICULT TO MACHINE
MATERIALS WITHOUT WEARING AWAY.
RED HARDNESS
— THE RELATIVE ABILITY OF THE STEEL TO WITHSTAND THE HEAT GENERATED WHEN CUTTING HARD MATERIALS
WITHOUT LOSING ITS HARDNESS.
M2 H.S.S. (ROCKWELL C63-65)
HAS THE HIGHEST TOUGHNESS AS WELL
AS GOOD WEAR RESISTANCE AND RED HARDNESS, AND IS ALSO THE
LEAST EXPENSIVE.
T15PM H.S.S. (ROCKWELL C64-66)
HAS HIGH WEAR AND ABRASION
RESISTANCE PLUS GOOD RED HARDNESS AND TOUGHNESS, AND IS
HIGHER PRICED.
76PM H.S.S. (ROCKWELL C65-68)
HAS THE HIGHEST WEAR RESISTANCE
AND RED HARDNESS PLUS GOOD TOUGHNESS, AND IS THE HIGHEST
PRICED. IT CAN BE USED WHEN NONE OF THE ABOVE STEELS ARE
SATISFACTORY.
SELECTING TOOL MATERIAL
M42 H.S.S. (ROCKWELL C65-68)
HAS HIGH RED HARDNESS PLUS GOOD
WEAR RESISTANCE AND TOUGHNESS, AND IS MEDIUM PRICED.
M4PM H.S.S. -
FORMERLY CALLED SUPERKUT
, (ROCKWELL C64-66)
HAS
HIGH WEAR RESISTANCE PLUS GOOD RED HARDNESS AND TOUGHNESS,
AND IS MEDIUM PRICED. WE PRESENTLY USE IT ONLY FOR CUTOFF BLADES
BECAUSE IT HAS PROVEN TO OUTPERFORM COBALT TYPE BLADES.
OTHER FACTORS TO CONSIDER IN SELECTING A TOOL MATERIAL ARE THE LENGTH OF THE RUN, THE TYPE OF MATERIAL BEING MACHINED, THE
CONDITION OF THE MACHINE, THE TYPE OF COOLANT BEING USED, TOLERANCES AND FINISHES REQUIRED, AND THE PERSONNEL OPERATING THE
MACHINES.
AND OF COURSE TO ATTAIN LONGEST TOOL LIFE, OR WHEN ALL ELSE FAILS, THE USE OF CARBIDE TOOLING IS THE ULTIMATE CHOICE.
WE RECOMMEND THAT, RATHER THAN STANDARDIZING ON ANY SINGLE MATERIAL, YOU ANALYZE EVERY JOB FOR THE MATERIAL WITH THOSE
CHARACTERISTICS BEST SUITED TO THE PARTICULAR REQUIREMENTS.
Since 1939 it has been the goal of Somma Tool Company to offer the best quality tools to the screwmachine industry.
We continue this tradition by offering the following new catalog items to help make your machines run more efficiently.
