1 TOOLS NEWS B225N & Grooving System Series New Product Long Lasting, Easy to Use & Grooving System

2 Simplified Series Simplicity & convenience. Introducing a new kind of cutting off & grooving system that maximizes usability without sacrificing machining performance.

3 Efficiency

4 Easy to Utilize Configuration that Improves Tool Handling Clamp Simple insert clamping method offering high rigidity. Voice of Developer Just how easy is it to set an insert? With the use of a unique wrench, it is possible to locate and remove the insert with one simply action making it easier for use in the workshop. To prevent the insert from being pulled out during machining a reverse taper angle has been designed from the front of the insert, additionally the design also includes 3 large locating faces between the insert and the blade offering increased cutting edge reliability. The blade Reverse Taper Angle itself is made from a special alloy steel to suit this application. In respect to insert indexing a unique wrench is supplied to ensure ease when changing the insert. 3

5 Through Coolant Blade Increased wear resistance due to the use of 2 through coolant ejection holes. 2 through coolant holes supply the coolant to both the rake and flank face, leading to effective cutting edge cooling and increased wear resistance. Additionally this blade can also be used for both low pressure and high pressure coolant (7MPa). Voice of Developer How is it possible to reduce heat generation? The 2 coolant holes used in the blade are capable of using high coolant pressures of up (7MPa), this is achieved by using as large as possible a through coolant hole diameter. The ejection holes are located close to the cutting edge so as to improve the cutting edge cooling effect and increasing wear resistance. Coolant Ports Flexible set up possible with the use of 6 coolant ports. There are 6 coolant ports designed into the tool block. This makes it easier for the end user to set up the tool block and blade to a configuration that suits their needs. If necessary it is also possible to use coolant hose. The ejection type coolant also improves cutting edge cooling and chip evacuation. Coolant Port Coolant Port (For Square Shank Adapter) Coolant Port Coolant Outlet Voice of Developer Possible to set up to suit the requirements of the workshop environment. One of the objectives of this product is to respond to the customers complaints that the product did not fit and could not be used. Starting with the coolant outlet that prevents leaks even when oil quantity or overhangs change, everything from the material and the shape of the O-ring, to the length of the hose has been tailored to the effective use in the workshop. 4

6 Clamp Mechanism Simple Insert Clamping Method Offering High Rigidity Highly Reliable Insert Clamping Convex geometry ensures high precision clamping. Reverse taper clamp prevents the insert from coming out. Safety key prevents insert movement. Easy Insert Indexing The inserts can be indexed easily with a one action movement of the wrench. Excellent Clamp Durability High clamp durability when compared to a conventional tool. 400 Number of Indexing (times) Conventional Based on a 3mm width insert. * 5

7 Internal Coolant Suitable for Various Set Ups Improving Tool Handling A scale is marked on the blade to make it easier to set the correct overhang length. (As long as the arrow of the blade is set up with an overhang length that is within the band on the tool block then through coolant is possible) The blade is possible to use with both external or through coolant. The insert can be located on either the left or right hand side of the blade.
