Gun Drills and Reamers

For General Purpose type of Gun Drill Machines, we keep a large inventory. The oil hole shape went through a model change from the old circle type of oil hole to a crescent type or double hole type for smoother cutting. We keep an inventory from 2mm - 32 mm, the maximum length will be up to 2150L which allows us to ship on the same date with the reception of the purchase order.

This is a new product with a coating process done on all of the carbide tip section. The coating process will allow the drill to be applied with high efficiency for difficult type of material such as Stainless Steel type material, Inconel type of material, Titanium type of material and aslo can be applied for work material with high hardness. 

Even for regular type of material, this coating process will allow better tool life, and application such as using water-soluable type coolant shows better results with using this type of gun drills.

Another characteristic of using this type of drill is the better outcome of the surface roughness, hole diameter will dramatically increase in efficiency, which allows the gun drill to finish a high demand application in one process.

We keep a standard inventory from 2mm - 12mm and can be shipped on the same day of the reception of purchase order.

Also as an option, we can manufacture with TiCN and TiALN coating.

The MVR Gundrills was developed to be attached on a machining center, NC lathe and other type of general purpose machines.Also, the MVR gundrills have a MIROKU's orginal chip breaker which will form a cutting chip like a small shell like shape for cutting general steel material which allows a deep hole drilling to be possible under low coolant pressure environment.

Also a guide hole will be used so a guide bush nor a guide plate is not necessary.

We keep a stock for 5mm -15.5mm and can be shipped on the same day of the reception of the purchase order.

And we will manufacture other sizes as well.
