Reduce processing costs through high-performance tools

With our high-performance reamers we provide higher cutting values quicker than the usual slow processes. Our range of high-performance drills is perfectly matched to the high-quality materials used in mould and die making.

Reaming becomes a high-performance process

The production of high-precision holes with tightest tolerances and perfect surface quality is usually achieved by reaming. This process has always been very slow and therefore not very popular in our fast-paced world.

With our new high-performance reamers, the reaming process becomes a high-performance process. These reamers allow the highest cutting values and thus reduce the time required significantly.

Highest process reliability
Considerable reduction of processing time
Highest service life
Specifically for the materials in mould and die making
Use in hardened materials up to 67 HRC

Advantages:

Highest cutting values and service life
Best surfaces and very high accuracy
High process reliability
Very precise drilling behaviour
Perfectly coordinated to materials used in mould and die making

Important application criteria

Our range of high-performance drills is perfectly matched to the high-quality materials used in mould and die making. The deep hole drills are best suited for making the holes for cooling systems. In order to achieve a perfect result, we have put together a few tips for use.

Cutting values

Practice-oriented cutting values can easily be found in our cutting data calculator. With just a few clicks you have the application data for a wide range of materials. In the catalogue and online shop you will find the most important materials and the matching cutting values in a table.

Tool clamping

To achieve the best results in terms of concentricity, we recommend shrink fit and hydraulic expansion chucks for the solid carbide drills. Under optimum conditions, fitting accuracy (IT7-8) is possible. In combination with the very good surface quality, reaming is often unnecessary.

Cutting fluids

For carbide drills with inner coolant supply, we recommend a coolant pressure of 15 to 20 bar. Higher pressures of up to 40 bar are recommended for deep hole drills. With the correct coolant pressure, the hole can be drilled to the final drilling depth in one operation. A chip removal process should be avoided, because if chips are flushed into the hole, they increase the risk of breakage.

Solid drilling

Our carbide drills up to 8xD are suitable for solid drilling. For carbide drills from 12xD (WZB 10227) we recommend a pilot hole. Our WZB 114446 carbide NC-centre drill with an angle of 142° is best suited for centring.

Maximum drilling depth

A chip jam can cause tool breakage. To avoid this, a safe distance must be maintained between the groove outlet and the workpiece. In the table in our catalogue and in the online shop this value is indicated under ‘Tmax.’ for each tool. This increases process reliability during drilling.
