Product description

H7 solid carbide reamer — VHM TiSiN

Ø1–Ø20 mm · straight flutes · one piece in the selected size

H7 solid carbide reamer with a TiSiN coating for finishing holes. Select the cutting diameter, cutting length and overall length to suit the workpiece.

Reamer machining a hole

1. Reamer for through holes

The tool has straight flutes and is intended for reaming holes, including through holes. H7 identifies the accuracy class of this family. Refer to the selected size card for its exact dimensions and flute count.

Feature	Specification
Tool type	Solid carbide reamer
Accuracy designation	H7
Material	VHM — solid carbide
Coating	TiSiN
Flutes	Straight
Sales unit	1 piece of the selected variant

2. Applications and workpiece materials

The reamer is intended for machining steel, tool steel, cast iron and stainless steel. The application range also includes aluminium and copper. The maximum workpiece hardness is 55 HRC. Consider the material condition when selecting the tool for hardened or quenched-and-tempered parts.

Material group	Application scope
Steel and steel sheet	Hole reaming with workpiece hardness taken into account
Tool and mould steel	Machining within the 55 HRC limit
Stainless steel	Hole reaming
Cast iron	Hole reaming
Aluminium and copper	Hole reaming
Hardened parts and quenched-and-tempered steel	Only within 55 HRC; check the actual workpiece hardness

3. Material and cutting section

The body is made of fine-grained VHM tungsten carbide. The grain size is 0.6 μm, and the cutting section has a TiSiN coating. The flutes are straight, precision-ground and polished.

Construction feature	Details
Carbide	Fine-grained VHM, 0.6 μm grain size
Cutting section	TiSiN coating
Flute geometry	Straight; execution for through holes
Flute finish	Ground and polished
Number of flutes	3, 4 or 6 — depending on the selected variant

4. Dimensions and variant selection

Dimensions are given in millimetres. The family covers cutting diameters from Ø1 to Ø20 mm, with different cutting and overall lengths. Not every diameter is offered in every length. When selecting a tool, compare the full variant designation with its dimension card.

Parameter	Family range / how to read it
Cutting diameter D	Ø1–Ø20 mm
Cutting length l	15–100 mm; use the value for the selected size
Overall length L	38–150 mm; use the value for the selected size
Number of flutes	Final designation 3T, 4T or 6T
Dimensional unit	mm

5. How to read the size designation

Example: 2x25x50L - 4T. The successive numbers identify the cutting diameter, cutting length and overall length. The number next to T indicates the flute count.

Example element	Meaning	Value
2	Cutting diameter D	Ø2 mm
25	Cutting length l	25 mm
50L	Overall length L	50 mm
4T	Number of flutes	4

Cutting length and overall length describe different sections of the tool. Check both values when comparing standard and longer versions. The photographs on the cards are illustrative: read the dimensions from their labels and table rather than measuring the photograph.

6. Machine tools and preparation

The tool is used on lathes, machining centres, and milling and drilling machines. Select a holding arrangement suitable for the machine and tool size. Before machining, check the diameter, available cutting length and workpiece hardness.

Machine type	Application
Lathe	Reaming operations
CNC machining centre	Hole machining
Milling machine or milling/drilling machine	Reaming operations with suitable toolholding

Select machining parameters according to the material, diameter and machining conditions. Overall length alone does not define the cutting section length: use the cutting length parameter for that value.

7. Sales unit and special sizes

The selected variant is sold as one reamer. The selected size determines the diameter, lengths and flute count of the tool supplied.

Item	Information
Contents	1 reamer in the selected size
Non-standard sizes	Diameters in 0.01 mm increments may be possible within selected ranges — confirm before ordering

If the diameter you need is not shown in the selector, contact us. Specify the required diameter, cutting length, overall length and accuracy. The parameters and availability of a special size require individual confirmation.

8. Frequently asked questions

Does every reamer have six flutes?

No. This family includes 3-, 4- and 6-flute executions. The T designation in the selected size name indicates the flute count.

Are straight flutes suitable for through holes?

Yes, this is an indicated application for this geometry.

What is the difference between cutting length and overall length?

Cutting length refers to the cutting section. Overall length covers the entire tool, including the shank.

Can I order a non-standard diameter?

A special execution requires individual confirmation. Diameters in 0.01 mm increments may be possible within selected ranges; agree the lengths and accuracy before ordering.
