Product description

3PKT indexable milling cutter with cylindrical shank

1. Indexable cutter with cylindrical shank

The 3PKT cylindrical-shank milling cutter uses replaceable cutting inserts. The cutting head and shank form one tool; select the insert for the pocket family, 3PKT10 or 3PKT15.

The body is made of 42CrMo alloy steel. Induction hardening provides hardness and resistance to deformation. Replaceable cutting inserts are secured by screws in the pockets.

Parameter	Information
Tool type	Indexable milling cutter
Mounting	Cylindrical shank
Body material	42CrMo alloy steel
Heat treatment	Induction hardening
Insert families	3PKT100408 / 3PKT150508, depending on variant

Cutting inserts are sold separately. Images show inserts fitted to illustrate their position in the pockets. This does not mean inserts are supplied with the body.

2. Applications and insert selection

This tool family is intended for roughing and finishing. Applications include face, shoulder and side milling. Compare the selected cutter geometry, mounting dimensions and insert type before making a selection.

Selection factor	Purpose
Body and mounting	Define the cutting diameter and the connection to the toolholder.
Replaceable insert	Its type must match the pocket of the selected body.
Insert grade and geometry	Selected for the workpiece material and type of operation.
Number of teeth	Specified in the designation and on the particular variant card.

The body code does not specify the insert grade. When purchasing inserts, consider the workpiece material and required operation; the cutter card identifies the matching insert type.

3. Dimensions and configurations

Cutting diameter and shank diameter are separate parameters and may be equal or different. Overall length includes the complete cutting head and shank.

Parameter	Range / meaning
Cutting diameter D	Ø16–Ø40 mm
Shank diameter C	Ø16, Ø20, Ø25 or Ø32 mm
Overall length L	90, 115, 150 or 200 mm
Number of teeth T	From 1 to 5, depending on the selected body

Dimensions are offered in specific combinations, not every possible combination. The selected variant card shows the correct set of D, C, L and T.

The 3PKT15 family includes distinct body configurations with different appearances. Use the complete designation when selecting the tool; cutting diameter alone does not identify its configuration.

Images are illustrative. Select the tool using the dimensions and designation of the chosen variant rather than proportions in the photograph. The variant card states the cutting diameter, length and number of teeth.

4. Reading the designation

Example: 3PKT10-D20-C20-150-2T. The designation includes the insert family and basic tool dimensions.

Code element	Meaning in the example
3PKT10	Body family for a 3PKT100408 insert
D20	Ø20 mm cutting diameter
C20	Ø20 mm shank diameter
150	150 mm overall length
2T	Two teeth

Some designations reverse the order of the C and D elements. D still refers to cutting diameter and C to shank diameter. Do not interchange these values when selecting the toolholder.

5. Inserts, screws and keys

Family	Insert	Screw	Key
3PKT10	3PKT100408	M2.5 × 6	T8
3PKT15	3PKT150508	M4.5 × 10	T20

Select the insert by its pocket designation and the screw and key using the table for the relevant family. The number of teeth specifies how many pockets are populated in the selected cutter.

The screw secures the insert in the body. Its size is not the tool shank diameter. T8 or T20 identifies the key used for the insert screw.

Cutting inserts are sold separately. Images show inserts fitted to illustrate their position in the pockets. This does not mean inserts are supplied with the body.

6. Mounting selection and servicing

Item to check	What to compare
Tool shank	Diameter C against the toolholder connection.
Cutting head	Diameter D against the required cutting diameter.
Length	Overall length L specified for the selected variant.
Insert pockets	Insert type, correct screw and proper seating.

Accurate insert seating and clamping in the pocket are part of the tool design. During servicing, check insert contact and the condition of the screw and pocket. Do not select fastening parts solely from the similar appearance of another cutter body.

7. Insert wear and machining checks

The condition of replaceable inserts affects part dimensions and surface quality. The following points distinguish common symptoms; process settings must be related to the workpiece material, insert and clamping rigidity.

Symptom	What to check
Gradual surface deterioration or dimensional change	Insert flank wear and cutting speed. For excessive wear, review the cutting parameters and insert grade.
Edge chipping	Insert selection, machining parameters, workpiece rigidity and correct insert clamping.
Sudden insert or tool failure	Insert seating, vibration, setup rigidity and loading from feed and cutting conditions.
Built-up edge and uneven surface	Cutting speed, feed and insert sharpness. Adjust parameters and cutting-edge geometry for the workpiece material.

Do not use one set of parameters for all workpiece materials and insert grades. T denotes the number of teeth, not a recommended spindle speed or feed.

8. Questions and answers

Are inserts included?
No. Purchase the insert type shown on the selected variant card separately.

Do D and C mean the same dimension?
No. D is cutting diameter and C is shank diameter. Their values may differ.

What does the number before T mean?
The number of teeth on the body. It is not the number of tools in a pack.

Does every 3PKT cutter use the same insert?
No. This listing includes families for 3PKT100408 and 3PKT150508 inserts. Match the insert to the specific body designation.

Can length be determined from the photograph?
No. The image is illustrative; the correct length is stated numerically on the card and in the variant designation.
