TAP SHANK & SQUARE DIMENSIONS

Kennedy® Thredfloer Fluteless Taps

Form rather than cut the thread in almost any ductile material. These include aluminium, brass, copper, carbon steels, zinc and magnesium alloys and even some stainless steels. The material is "cold formed" into the relevant thread and has the advantage of being a full form thread unlike normal cut tapped holes. This make the thread stronger. The forming operation does not create chips so swarf contamination and blockage is illiminated and tap breakage reduced. Because there is no consideration for chip evacuation, Thredfloer taps can be run at higher cutting speeds and reduced cycle times. Lubrication grooves are a feature of all Thredfloer taps of M3.0 and over. These allow lubrication to reach the end of the tap to maintain tool life and to prevent damage from "Hydraulic Blow Out".

EP30 DIN 2184-1 Spiral Point UNF Taps

Bright Finish

Dormer Machine Taps

MTT-X taps are manufactured from premium quality vanadium powder steel, branded HSS-XS1, for an unbeatable combination of toughness, edge strength and wear resistance. This winning combination enables them to withstand the stresses of threading in tough materials. Special gold finish with bright flutes/thread, or steam tempering (blue) guarantee a smooth cutting action with less build-up on the cutting edge.

For all dimensional specifications please refer to our catalogue.

ISO Metric: E000 Spiral Point (Gold Coated)

For through holes. Taper lead to DIN form B. Tapping tolerances to 6H. Max depth 2.5 x D.

Guhring GT100 Extra Long Drills HSS

Robust tool for use in difficult conditions in extremely deep holes when swarf congestion prevents an adequate flow of coolant. For use in steels and cast iron having a tensile strength of up to 1000N/mm2. Manufactured to DIN1869.

For all dimensional specifications please refer to our catalogue.
