Introduction on insert drill in BTA application
Our company can provide full drilling solutions for customer on both drilling machine, lathe machine and VMC. Most importantly, Insert drill in BTA application, we can assist customer for better optimization of customer’s existing drilling application.
An insert drill is a side or end-cutting tool that has a cutting edge. The tool also has helical or straight grooves for chips to pass through, as well as a nozzle for admitting coolant. This type of drill is also called an indexable-insert drill. The insert's cutting edge is used until it becomes dull, and then the insert is indexed to expose a new cutting edge. The dull cutting edge is then discarded.
Design of Insert Position on the BTA Drill
When looking for the right insert for a drill, manufacturers should consider the operating environment and the material being worked on. For instance, a drill made of high-hard steel may require a different insert than one made of cast iron. For this reason, it is essential to understand the material being worked on before making a purchase.
The cutting inserts of an insert drill are aligned radially with respect to the central axis of the drill body. This allows the cutting inserts to be positioned at various radial locations. This arrangement makes it easier for the operator to change the cutting inserts without disturbing the other parts of the drill.
Case Study from India customer to optimize the long chips issue caused by central insert design
Component material: Alloy steel 4130
Our Improved Design:
Shifting the central insert position and strengthen the guide pad area
Customer’s Feedback after Optimization
“I would like to inform that Dia 37 Deep hole drill head was tried and was partially successful i can say at this point. Please go through the below points.
1) Chip Breaking is good. Surface is smooth.
2) Drill head has been used to drill for a total length of 29.5" (750mm), drill head seems to be fine, no damage on the drill head. Head usage will be continued, to get the final result.
3) Material tried was Alloy Steel 4130 (Soft Material). They have 4330 material also to be tried which is more compared to 4130 material.”
Summary
Solid-carbide drills are a good choice for small jobs that are rarely repeated. They have a lower initial cost and reduce the need for downtime for changeouts. Their replaceable cutting edges can also lower CPC. This can be especially helpful if you are working on long-term contracts and need a tool for multiple applications.
Another advantage of an indexable insert drill is its interchangeability. They can be replaced much easier than solid drills, which require removing the drill from the toolholder to make the change. They can also be used in higher-volume metalworking and fabrication applications. This type of drill has many advantages and is worth considering if you need a more versatile tool for your machining requirements.
