Our patented product

MLT-Taps

This patented tool unites three functions into one tool. It is designed for pre-cast holes in ADC. While the thread
section at its tip opens the hole cylindrically the threading part cuts a clean thread. These two operations are followed
by a reamer that cuts the thread's internal diameter to the desired dimension. True multi-funtionality.

Technical Features

• MLT Taps are designed for working die cast parts suchas motor housings, carburator housings, and the like.

• They combine three functions into one single operation(Pictures 1.1/1.2) :1. Removing the cast surface from the die cast hole.2. Tapping the thread.3. Reaming the minor diameter of the thread to therequired one.

• To achieve this the cutting section of the MLT tap hasbeen combined with a special drilling/milling face and aside reamer (Picture 2.1).

• MLT Taps can be used in blind holes and through holes.In through holes with thin film bottoms, these bottomsare removed by MLT taps creating a clean, burr-less exitof the hole.

• From size M6 on MLT Taps are designed with internalcooling.

Advantages in Production

• MLT Taps are designed for working die cast parts suchas motor housings, carburator housings, and the like.

2. Tapping the thread.
3. Reaming the minor diameter of the thread to therequired one.

• From size M6 on MLT Taps are designed with internalcooling.

Application :

• All MLT taps should be used with synchronized tapping spindles only.

• Rigid tool holders without compensation should be used.

• Because MLT taps generate more chips than conventional taps internal cooling isrecommended. From size M6 all MLT taps feature centre cooling through the shank. Forsmaller sizes the TANOI „Side-Through-System“ is strongly recommended for cooling.

• The molded holes need to meet the minimum requirements
for use of MLT taps.
– The diameter of the hole at the entry should be according to the normal drill diameter forcutting taps. This is approximately the nominal diameter minus the pitch. For a tap M6 thehole’s diameter should therefore be 5.0 mm.
– The minimum diameter of the hole should be 0.6 x the nominal diameter of the thread. For atap M6 it should therefore be 0.6 x 6 mm = 3.6 mm.
– From these two values the incline of the molded hole may be calculated as shown in the picturebelow.
