DRILLSTAR CARBIDE TOOLS ARE WORKING IN MANY PLACES AROUND THE WORLD
Indexable gun drills have a machined steel shank and driver, with replaceable cutting inserts and wear pads.
These tools can achieve very high feed rates, and provide the convenience and economics of indexing the carbide insert and wear pad rather than sharpening the tool.
The drilled-hole diameter is typically less precise than a solid carbide gun drill or brazed gun drill, both of which have the head ground to the finished diameter, rather than relying on machined insert pockets with larger manufacturing tolerances.
The initial expense of the indexable tools is higher than a comparable brazed tool, so they are generally applied in higher volume applications.
13.5 – 50 mm [0.53 – 2.00 in]
Drills holes from solid
Internal Coolant
Material | Tungsten Carbide |
Type | Gun Drill Bit |
Model Number | Drillstar |
Brand Name | DR |
Place of Origin | Shandong, China (Mainland) |
Carbide | Originally from Switzerland |
Certification | CE,ISO |
Use | Metal Drilling |
Versatility for use on lathe, machining centers and deep hole machines.
High efficiency by specifically developed cutting edge geometry for chip formation
Shortens downtime resulting from quick exchange of worn parts
Easy to use, no sharpening, no length adjustment, easy inventory of wear parts.
Lengthens tool life due to full coating, edge treatment and indexable designs
Quick availability due to stocked wear parts and most common boy sizes.
Triangle inserts have 3 cutting edges. Positive rake chip breakers and chip splitting geometries allow the use of feed rates 3 to 4 times greater than that of traditional gun drills. They are manufaturered from micrograin carbide and available in several PVD wear resistant coatings.
