1. TECHNICAL CODE BREAKDOWN
A: DESIGNATES THE 85-DEGREE PARALLELOGRAM BASE PROFILE SHAPE, CONVEYING EXCELLENT SIDE FLANK RIGIDITY.
P: INDICATES AN 11-DEGREE POSITIVE CLEARANCE ANGLE, RADICALLY LOWERING SPINDLE FRICTION LOADS AND ELIMINATING TOOL CHATTER MARKS. [1]
K: REPRESENTATIVE NORMAL MANUFACTURING TOLERANCE CLASS GOVERNING THE INSCRIBED CIRCLE (IC) BOUNDARIES AND THICKNESS EXTRUSIONS FOR BALANCED MODULAR LOADING.
T: CONFIRMS A SINGLE-SIDED STRUCTURE WITH A COUNTERSUNK HOLE TAILORED FOR RECESSED CENTER-SCREW CLAMPING FIXTURES. [1]
17: IDENTIFIES THE HIGH METRIC CUTTING EDGE LENGTH SCALE OF 17.00 MM (SUITABLE FOR DEEP RADIAL DEPTH PASSES UP TO 15–16 MM).
04: SPECIFIES THE NOMINAL COMPONENT BODY THICKNESS RATIO EQUAL TO 4.76 MM.
20: DESIGNATES A HEAVY-DUTY CORNER NOSE RADIUS OF 2.0 MM, WHICH ENHANCES EDGE STRENGTH TO SURVIVE IMPACT-HEAVY INTERRUPTED CUTS.
4340: THE PREMIUM COATING GRADE (STANDARDISED IN SPHERES DEPLOYED BY BRANDS LIKE SANDVIK COROMANT), COMBINING A TOUGH GRIT BASE COMPOSITE WITH A CVD TiCN + Al₂O₃ + TiN TRIPLE-LAYER MATRIX. IT IS EXCLUSIVELY ENGINEERED FOR PRE-MACHINING AND RELIABLE HEAVY-DUTY OPERATION IN HIGH-ALLOY STEELS. [1]
R31: THE BRAND-SPECIFIC CHIPBREAKER GEOMETRY IDENTIFIER, OPTIMISED FOR EXTENDED SHEAR STABILITY AND SYSTEMATIC FLUID CHIP EVACUATION UNDER EXPEDITED HOLE RAMPDOWN FEED VELOCITIES.
2. KEY ATTRIBUTES & DESIGN
HEAVY SHOULDER EDGE STABILITY: CONSTRUCTED WITH A ROBUST 2.0 MM RADIUS PROFILE TO SPREAD THE THERMO-MECHANICAL IMPACT ACROSS A BROADER RADIAL FACE, DRAMATICALLY PREVENTING MICRO-FRACTURES AT THE TIP.
CVD HEAT BARRIER IMMUNITY: THE HIGH-THICKNESS ALUMINIUM-OXIDE (Al₂O₃) COATING ACTS AS A THERMAL SHIELD, ALLOWING HIGH VELOCITY MILLING PARAMETERS EVEN WHEN DRY CORING HIGH-TENSILE STEELS AT EXTREME OPERATING TEMPERATURES.
HELICAL PLUNGE CAPABILITY: THE INTEGRATED POSITIVE EDGE RAKE CUTS EFFORTLESSLY, SUPPORTING COMPLICATED AXIAL STEPPED SLOTTING AND HELICAL INTERPOLATION IN ENCLOSED MACHINING POCKETS. [1]
3. INDUSTRIAL APPLICATIONS
TARGET PROCESSES: 90° SQUARE SHOULDER MILLING, HEAVY SLOTTING CHANNELS, PLUNGE RAMPDOWN RUNS, PROFILE CONTORING, AND ROUGH FACE PLANING.
COMPATIBLE HOUSINGS: ARBOR SLEEVES, LARGE SECTION LIVE INDEXABLE MULTI-FLUTE END MILLS, AND SHELL MILLING HEAD CUTTER HUBS RATED FOR 17 MM PROFILE POCKET SEATS.
COMMON WORKPIECES: HIGH-ALLOY CHROME-MOLY TRUCKING AXLES, MACHINED GEAR RAILWAYS, HEAVY DIE AND MOULD BLOCKS, AUTOMOTIVE ENGINE BASES, AND PETROCHEMICAL REFINERY CORROSION FLANGES. [1, 2]
