Standard Cut - Normal - Standard - Estandar

This fluting pattern is considered standard for the Menlo Tool Co. Flute structure is designed for both superior material removal and a smooth finish. The common use of the "standard cut" is on steel, steel alloys, cast iron, some copper and brass, and generally where the material is relatively hard and will not load the flutes.

Chip Breaker - Spanbrecher - Copeaux- Utas

The addition of a chip breaker on the three single spiral flute patterns - standard, coarse, fine - will benefit the operator in two ways. First, there will be an improvement in tool control. Second, the chips will be broken up to reduce sliver size. Surface finish will be slightly reduced due to chip breaker pattern.

Coarse Cut - Grob - a Grand Rendement - Amplio

This style of flute structure is recommended for use on soft materials that would normally load the standard cut. With this flute design, rapid stock removal in materials such as copper, brass, aluminum, plastics and rubber are achieved. If loading is excessive, then the aluminum cut style is recommended. Here, extremely fast stock removal is possible on the softer nonferrous materials. The extra deep flute structure should eliminate burr loading.

Fine Cut- Fein - Fine - Fino

Selection of fine cut should be based on the required finish. While stock removal is reduced the finish is greatly improved. This cut is recommended only on materials having a Rockwell "C" hardness in the range of 55-60.

Double Cut- Kreuz- Croisse - Cruzado

The double cut burr allows for rapid stock removal in the harder materials. This chisel tooth pattern not only minimizes tool chatter but reduces the chip to a granular shape, in most materials, thereby reducing or eliminating the sharp sliver chips that are normally experienced. This chip reduction also helps to eliminate loading of the flutes. An improvement in tool control will be realized as the double cut tends to reduce the pulling action of the main flute pattern. Although some finish reduction may be experienced, improvement in material removal and, therefore, increased production will be realized.

Diamond Cut- Diamant- Diamant- Diamante

The diamond cut flute pattern produces teeth with a triangular style of point. This greater number of teeth will produce extremely small chips. The diamond cut virtually eliminates the pulling action of the main cut thereby greatly improving tool control. With this cut, stock removal will be greatly increased at the sacrifice of finish.
