Product description

90° chamfer mill — solid carbide, NaCo4, 2 flutes

Cutting diameters Ø1–12 mm · overall lengths 50–75 mm

A solid carbide chamfer mill with a NaCo4 coating and two flutes. Its 90° included angle makes it suitable for chamfering edges. It can also be used for deburring and spotting before drilling.

When selecting a size, check cutting diameter, shank diameter and overall length separately. In particular, the smallest sizes have a shank larger than the cutting section. Dimensions for the selected tool are shown on its variant card.

1. Applications

Chamfering edges — producing chamfers on external part edges and at hole entrances.
Deburring — removing burrs left by previous machining operations.
Spotting — preparing an entry point before drilling, taking the geometry of the following tool into account.

Workpiece materials: steel and stainless steel. Select cutting conditions for the specific grade and material condition. The tool is intended for milling machines and machining centres.

2. Technical specifications

Parameter	Value
Tool type	Solid shank chamfer mill
Tool material	VHM — solid carbide
Coating	NaCo4
Number of flutes	2
Included angle	90°
Cutting diameter	Ø1–12 mm, depending on the variant
Shank diameter	Ø3–12 mm, depending on the variant
Overall length	50, 60 or 75 mm, depending on the variant
Sales unit	1 piece

These ranges describe the series. Available size combinations are shown in the variant selector. Not every cutting diameter is available with every length.

3. Understanding the 90° angle

90° is the full included angle of the tool. In an axial section, each side of the cone is at 45° to the axis. The included angle should not be confused with the angle of one side of the chamfer.

Cutting diameter does not determine the finished chamfer width. Its size also depends on the tool position relative to the edge and the selected machining depth.

4. Reading the variant size

Example: 4x50Lx2Tx90°. The code elements mean:

Code element	Meaning	Value
4	Cutting diameter	Ø4 mm
50L	Overall length	50 mm
2T	Number of flutes	2
90°	Included angle	90°

Shank diameter is not a separate element of this code. Check it on the variant card before selecting a holder. The Ø1 mm and Ø2 mm cutting sizes have a Ø4 mm shank. Overall length L is not cutting length. Dimension illustrations are schematic and are not to scale.

5. Selection and working conditions

Match the shank to the holder. Do not choose the clamping diameter solely from the first number in the code.
Select the diameter for the part geometry. Consider the planned chamfer, edge access and holder clearance.
Keep overhang short. Use the shortest practical overhang for the job. Check shank cleanliness, holder condition and runout after clamping.
Set conditions for the actual operation. Speed, feed, depth and cooling or lubrication depend on the workpiece material, chamfer size and system rigidity.
Consider the following drill when spotting. Select the spot angle and depth to suit its geometry and drilling recommendations.

6. Order contents and questions

You receive 1 solid carbide NaCo4 chamfer mill with two flutes and a 90° included angle, in the selected size. The order quantity specifies the number of tools of that variant.
