Solid carbide end mills

Selecting an end mill: What should you look out for?

The four different HAIMER MILL series for cutting tools and the new HAIMER Panther MILL have been developed for different applications.

Starting with the HAIMER MILL line, our strong all-round tool especially for drilling and ramping in all materials, through to the HAIMER Panther MILL, a sporty all-rounder in steel and stainless materials for trimming and grooving. The HAIMER MILL Power series is also suitable for high-performance milling in steel, while the special HAIMER MILL Alu series is the specialist for wrought aluminum alloys and plastics. Finally, the HAIMER MILL HF series stands for high feed rates in steel machining.

HAIMER Panther Mill

HAIMER Panther MILL is the absolute all-rounder for trimming and grooving in all steel and stainless materials.

Four cutting edges with unequal pitch and unequal helix provide extremely smooth running.

Thanks to the latest coating technology, the milling cutter adapts perfectly to its environment like a panther, increasing tool life by 30 to 40% compared to conventional coatings.

The optimized cutting edge geometry and the adapted helix angle of 36°/38° ensure optimum chip evacuation and therefore perfect surface quality and high process reliability.

HAIMER MILL

The HAMER MILL line focuses on the essentials in terms of product characteristics and represents our entry level cutting tool when it comes to efficient machining. Simultaneously, it offers through HAIMER quality the best price-performance ratio possible.

HAIMER MILL solid carbide end mills can be used in almost all materials and are primarily suitable for roughing and finishing operations. A huge variety of chamfering end mills completes the HAIMER MILL line portfolio.

HAIMER MILL Power Series

With the HAIMER MILL Power Series we offer a solid carbide end mill program for demanding milling strategies corresponding to our tool holder program.

They have been designed for universal applications in various materials. Especially in steel applications the geometries convince with their long tool life and a consistent high surface quality.

The HAIMER MILL Power Series is based on a pure submicron carbide grade with excellent transverse rupture strength (T.R.S.) combined with the most modern coating technology (e.g. AlTiN-based PVD coating).

All HAIMER MILL Power Series end mills are fine balanced and available with the well-known Safe-Lock pull out protection system from shank diameter 6 mm onwards – for highest process reliability in milling.

Shank tolerance: h6
Neck for higher cutting depth
Center cutting
Runout < 10 μm
Available with straight shank, Safe-Lock or Weldon shank

HAIMER MILL Alu Series

The HAIMER MILL Alu Series end mills have been developed for applications in aluminium. However, these cutting tools are also recommended for machining brass, copper and plastic.

The micro-geometry of these milling cutters is specially designed for smooth running and surface finish. These cutting tools are suitable for high cutting speeds and feed rates. They generate high removal rates and can therefore be used in roughing and finishing applications.

HAIMER MILL Alu Series is fine balanced and provides maximum reliability at high speeds thanks to their vibration-free running.

For materials with highly abrasive character, the HAIMER C coating is recommended. This wear-resistant, titanium-free PVD coating increases the life time of the cutting tools.

Shank tolerance: h5

Center cutting
Runout < 5 μm

HAIMER MILL HF Series

The solid carbide end mills of the HAIMER MILL HF Series have been developed for the highest feed rate speeds in steel applications. In addition, the tools can be used for applications in stainless steel, cast iron, aluminium alloys, titanium alloys and hardened steel.

Due to the special face geometry, maximum feed rates can be achieved with simultaneous dissipation of the axial forces in the direction of the spindle axis, which ensures optimum load distribution.

Air or coolant can be fed through central cooling bores of the cutting tool. This prevents chip accumulation, cools the cutting edge reliably and thus, increases the tool life.

Because of a very high runout accuracy of < 5 μm and a balance quality of less than 1 gmm, the milling cutters are also ideally suited for highest speeds and therefore protect your machine tool by low vibration inclination.

MILLING STRATEGIES AT A GLANCE

Common milling strategies are e.g. face milling, corner milling, groove milling and profile milling.

All milling cutters of the HAIMER Mill Series are a good choice when face milling or corner milling. HAIMER MILL milling cutters are also particularly reliable during groove milling due to their cutting edge geometry.

HAIMER Mill Power Series full radius and corner radius milling cutters are suitable for profile milling, as their narrow radius tolerance produces particularly high contour fidelity & fine surfaces.

Thanks to its stable face and flank geometry, the HAIMER Panther MILL is particularly suitable for corner milling, slot milling and profile milling.

EXAMPLES OF MODERN MILLING STRATEGIES

HAIMER milling cutters are also suitable for demanding milling strategies. In our product range you will find the right milling cutter for your production. HAIMER milling cutters ensure fast, precise machining and beautiful surfaces.

For HPC strategies (High Performance Cutting) for high material removal rates, you need stable milling cutters. The HAIMER Mill Power Series is characterized by increased stability and concentricity. Choose a cutter with a long neck for a longer cutting depth. The HAIMER Panther MILL also impresses with its stability and optimized helix angle at high metal removal rates in HPC milling.

For HSC strategies (High Speed Cutting) with particularly high speeds, we recommend our customers to choose balanced milling cutters, because a high balancing quality and thus a low-vibration concentricity not only increases the service life of your tool, but also ensures high-quality surface results. All Power Series milling cutters are finely balanced < 1 gmm and have a concentricity of < 5 μm.

Highly dynamic milling is a milling strategy also known as trochoidal milling or trochoid milling. With this strategy, you pursue the goal of achieving high cutting depths with high feed rates at the same time. Due to constant center chip thickness, this strategy is particularly gentle on the cutting edge of the milling cutter, which has a positive effect on its service life.The high cutting depth results in long chips. To ensure process reliability, we recommend a milling cutter with chip breaker function. The chips are reduced, which leads to improved chip removal in the milling process. Both the HAIMER Panther MILL and the HAIMER MILL Power Series are ideally suited to these modern strategies. The HAIMER MILL also offers optimum results for applications with cutting edge lengths of up to 3xD.

Our tip: choose an end mill with Safe-Lock technology to counteract high axial extension forces.
