Shark Line application taps

INTRODUCTION • Dormer’s application-based ranges of DIN taps, branded Shark Line, are renowned for their high performance and are easily recognisable by their coloured rings, denoting recommendation for use on specific materials. • Research has led to the development of new features on specific Shark Lines, such as special coatings and geometries. • Shark Line taps are a dependable solution when high quality threads are required in specific materials. FEATURES • APPLICATION Problem-free threading of blind and through holes in specific materials. • COLOUR RING CODING The colour ring identifies...

TOOL MATERIAL • Shark Line taps are manufactured from special powder metalurgy tool steel (HSS-E-PM). This provides an unbeatable combination of toughness and edge strength allowing increased hot hardness properties, resulting in excellent performance under higher cutting conditions.

YELLOW SHARK • DESIGNED FOR HIGH PERFORMANCE THREAD PRODUCTION IN LOW ALLOY STEELS. • SURFACE TREATMENT Available with Hard Chrome Plating (Cr) to prevent built up edge when tapping materials which are prone to sticking to the cutting edges. Yellow Shark also has an additional edge treatment to guarantee excellent performance in steels. • FLUTE GEOMETRY Available in spiral point for through holes and spiral flute (40° angle) for blind holes. Special flute geometry on Yellow Shark spiral flute taps means the nest formation of swarf is prevented, reducing the risk of re-cutting swarf on reversal....

BLUE SHARK • DESIGNED FOR HIGH PERFORMANCE THREAD PRODUCTION IN A WIDE RANGE OF STAINLESS STEELS. • SURFACE TREATMENT Available in Steam Tempered (ST) or Super-B (TiAlN + WC/C) coating combined with an additional edge treatment guarentees excellent performance in most stainless steels. • FLUTE GEOMETRY Available in spiral point for through holes and spiral flute (40° angle) for blind holes. • BACK TAPERED On the E238 and E239 spiral flute Blue Shark, the back taper further facilitates chip evacuation, reducing chipping on the last threads of the taps and also reducing the torque when the tap...

GREEN SHARK • DESIGNED FOR HIGH PERFORMANCE THREAD PRODUCTION IN NON-FERROUS MATERIALS. • SURFACE TREATMENT Available in Bright Finish or Super-B (TiAlN + WC/C) coating guarantees excellent performance in aluminiums, brass and copper. • FLUTE GEOMETRY Available in spiral point for through holes and spiral flute (35° angle) for blind holes. Special flute geometry on Green Shark spiral flute taps means the nest formation of swarf is prevented, reducing the risk of re-cutting swarf on reversal. Metric Spiral Point - Bright E471 from M3 to M20 Spiral Point - Super-B E472 from M3 to M20 Spiral Flute...

SPECIAL FLUTE GEOMETRY • Special shaped grinding wheels create a flute geometry on spiral flute Shark taps to help control swarf, preventing nest formation and re-cutting of swarf on reversal. HINTS & TIPS • Rigid tapping is recommended particularly when tapping blind holes with spiral flute taps. • When rigid tapping on CNC machines with Shark taps, it is recommended to use a synchronized tool holder with minimal float or soft start. • If rigid tapping using ER collet chucks, it is recommended to use collets with square drive. This will reduce the chance of slipping and increase tool life. •...

SUPERIOR CUTTING EDGE STRENGTH • HSS-E-PM has a more controlled structure which provides more uniform wear and therefore delivers more consistent performance and process stability. Essential when tapping. Minimal lead wear after many holes E261 M8 after 1600 Holes in Steel Uddeholm Orvar Supreme (AMG 1.5) Vc = 20 M/min Depth = 20 mm E390 M8 after 10000 Holes in Cast Iron SS0727 (AMG 3.3) Vc = 35 M/min Depth = 16 mm CUTTING FLUIDS FOR SHARK LINE TAPS Brass/ Copper Alloy steels Stainless Steel
