4. Standards for Toolholders
4.1 The first digit
Clamping system
A line contact is being used on the pocket wall for locating inserts in the pocket of the toolholder.
An unthreaded cam pin is used as locking member. Various tool manufacturers have patents on this method.
Top clamping method is there. There is hole clamping also.
4.2 The second digit
insert shape
4.3 The third digit
Toolholder type in relation to entering angles
The entering angle is referred to as cutting edge angle. Smaller cutting angles are preferred.
1. The cut is spread over a broader section of the cutting edge.
2. It has greater heat dissipating capacity
3. It protects the tool nose radius area.

Cutting Tool Technology: Industrial Handbook
Graham T. Smith
Springer Science & Business Media, 03-Jul-2008 - Technology & Engineering - 600 pages
Cutting Tool Technology provides a comprehensive guide to the latest developments in the use of cutting tool technology. The book covers new machining and tooling topics such as high-speed and hard-part machining, near-dry and dry-machining strategies, multi-functional tooling, ‘diamond-like’ and ‘atomically-modified’ coatings, plus many others. Also covered are subjects important from a research perspective, such as micro-machining and artificial intelligence coupled to neural network tool condition monitoring. A practical handbook complete with troubleshooting tables for common problems, Cutting Tool Technology is an invaluable reference for researchers, manufacturers and users of cutting tools.
