A chamfer mill is a conical cutter for breaking edges, chamfering and countersinking. Its defining feature is the cutting-edge (point) angle.

Main cutting geometry
Cutting edge angle KAPR
|
The angle of the conical cutting edge. The defining feature of the tool: it sets the angle of the chamfers it can produce (e.g. a 45° chamfer mill). |
Cutting diameter maximum DCX
|
The largest diameter the cone cuts at. With the edge angle, it defines the cutting profile. |
Cutting diameter DC
|
The cutting diameter at the reference point; a driver of feeds and speeds. |
Depth of cut max APMX
|
The deepest the tool can cut in a single axial pass. |
Flute count ZEFP
|
Number of cutting edges around the periphery. Directly scales the feed rate. |
Non-cutting geometry
Overall length OAL
|
Total length from the holder face to the tip. |
Connection diameter machine side DCONMS
|
The shank/connection diameter where the tool meets the holder. |
| Shank mode |
Basic for a simple neck, or Advanced for a stepped body profile. |
Neck diameter DN Basic |
Reduced neck diameter for clearance. |
| Body segments Advanced |
A multi-step body profile (diameters, lengths, taper angles). |
Protruding length LPR
|
The tool's default protruding length (stickout); assemblies can override it. |
Tool materials
Tool material BMC
|
The cutter substrate (e.g. carbide, HSS). |
Coating property CTP
|
Whether the tool is coated. |
Coating COATN
|
The coating name/designation, if any. |
Grade identification GRDID
|
The manufacturer's grade. |
Supplementary cutting geometry
Flute helix angle FHA
|
Helix angle of the flutes. |
Coolant supply CSP
|
Whether the tool has through-tool coolant. |
Connection code type machine side CCTMS
|
Standardised connection/interface code on the machine side. |
Optional details
Face edge count ZEFF
|
Number of cutting edges effective on the end face. |
Usable length LU
|
The length below the holder that can be brought into the cut. |
Tool assembly length LTA
|
Overall length of the assembled tool. |
Functional length LF
|
Functional length of the tool. |
Rake angle radial GAMF
|
Radial rake angle of the cutting edge. |
Ramping angle maximum RMPX
|
The steepest ramp angle the tool can plunge at. |
Profile radius PRFRAD
|
Radius of a profiled cutting form, if any. |
Center point of the profile radius, z-direction CPRADZ
|
The z-position of that profile radius's centre. |
Shank length LS
|
Length of the shank. |
Clamping length machine side LSCMS
|
Length clamped in the holder on the machine side. |
Flute length LCF
|
Length of the fluted (chip) section. |
Head length LH
|
Length of the cutting head. |
Cutting pitch differential CPDF
|
Whether the flutes use variable (differential) pitch. |
Cutting edge centre count ZNC
|
Number of edges that reach the centre. |
Chip breaker CBMD
|
Chip breaker's manufacturer designation, if fitted. |
