Along with the more and more precise development of CNC machine as well as more and more application of compound material, cutting tools play a more important role for machining. Traditional solid tool such as solid high-speed steel and solid carbide tool are replaced by indexable cutting tools for many items due to poor tool life or too expensive tool cost.

Several advantages of indexable cutting tool can effectively raise machining efficiency and lower cost:
1. Application of carbide insert. As teeth are worn out, it only needs to replace insert without abandoning the cutter body or regrinding it. It reduces problems of the instable life issue by regrinding. Meanwhile since carbide insert has always multiple edges available, the general cost among with the performance is lower than solid tools.

2. Indexable cutting tool has better shareability. The same carbide insert can be used on holder with different length or outer diameter. For example, the same insert mounted on dovetail cutter of 50° can also be mounted on dovetail cutter of 55° and thus saves the expense for tool cost.

## Indexable Dovetail / Aluminum Milling Cutter Series
- [Indexable Dovetail / Aluminum Milling Cutter Series | Milling Cutters | Y.T. / YT / YIH TROUN](https://www.cut-tools.com.tw/en/category/A06.html): Indexable Dovetail / Aluminum Milling Cutter Series supply. Along with the more and more precise development of CNC machine as well as more and more application of compound material, cutting tools play a more important role for machining. Traditional solid tool such as solid high-speed steel and solid carbide tool are replaced by indexable cutting tools for many items due to poor tool life or too expensive tool cost.

Several advantages of indexable cutting tool can effectively raise machining efficiency and lower cost:
1. Application of carbide insert. As teeth are worn out, it only needs to replace insert without abandoning the cutter body or regrinding it. It reduces problems of the instable life issue by regrinding. Meanwhile since carbide insert has always multiple edges available, the general cost among with the performance is lower than solid tools.

2. Indexable cutting tool has better shareability. The same carbide insert can be used on holder with different length or outer diameter. For example, the same insert mounted on dovetail cutter of 50° can also be mounted on dovetail cutter of 55° and thus saves the expense for tool cost.

With dovetail cutter and facemilling cutter for aluminum as examples, we design them as indexable carbide insert to help manufacturers to achieve better machining efficiency and thus raise the competitiveness on market. indexable cutting tool, milling, slotting and slitting tool manufacturer from Taiwan, since 1977.

- [How to reduce the machining cost in hole making - FAQs | Indexable Milling Cutters | Y.T. / YT / YIH TROUN](https://www.cut-tools.com.tw/en/faq/solution-faq-13.html): In these days of recession, it is hard for many customers to get orders or profitable orders. Many of users try to find the cheap HSS tools to reduce the tool cost even though they understood the toollife and performance are poor.  But if you calculate with more details together with performance and cost, you will notice cheap tools doesn’t really save the cost instead you pay even more.

Usually, spot drill is used in Pre-drilling which makes a spot to bring drill in a right and precise position. The more precise the spot drill, the more accurate the pre-hole, which reduce the risk of drill wear-out and tap breakage problem. In general, people try to avoid the possibility of tap breakage in machining, because tapping is usually the last process of the work. Once the tap breaks, it takes time to remove the broken tap, and it may cause the risk of entire workpiece to be scrapped. A customer from Y.T. used to use the indexable spot drill from other brand, but because of the eccentric is too big which cannot effectively play the role of spot drill, on average, a batch of workpieces will break about 7 to 9 taps. After using our precise spot drill, an average batch of workpieces break 1 to 2 taps. The overall calculation of an indexable spot drill with a precise eccentricity can reduce the risk of drill wear and tap breakage, greatly reducing your tool costs and increasing machining efficiency.


The following is a video of a customer's actual job. Even when making HRC42 harden steel, even if it is used on an unstable drilling machine, Y.T. carbide insert is still intact with good stability and speed. For the spot drill which is not accurate it has already brought chattering under this condition, it is impossible to drill deeper or faster and the workpiece are not possible by just holding by hand. Check the video https://www.youtube.com/watch?v=UrTM8c6Euss


Y.T. indexbale spot drill insert are fully grinded which is made by the carbide powder imported from USA. An actual test result from customer in machining stainless steel can reach more than 10,000 holes, with full depth it can reach 2,000 holes in stainless steel, video: https://www.youtube.com/watch?v=7r55lAGY1ys 


In addition, there are 3 different angles for spot drill insert: 90° / 142° / 90° + 142°. The 90° spot drill is a multi-function application. In addition to spot, it can also be used for various functions such as chamfering / engraving / V-grooving.
