Unidrill® Replaceable Insert Drill

Stellram Unidrill is the new replaceable insert drill for diameters from 0.3937" to 5.9055" (10,00mm – 150,00mm). Both HSS and carbide inserts are available.

Geometry XR, Grade SP9212
Diameter range 10,00mm – 65,00mm / 0.3937" – 2.5591"
(PM-HSS-Co with the latest AlTiN PVD coating). Economic and high wear-resistant cutting insert with positive geometry and excellent chip control feature. Insert geometry with constant cutting angle, chip splitters and corner protection. First choice for machining steel, cast iron, nodular cast iron and nonferrous metals.

Geometry XR Grade SP9412
Diameter range 66,00mm – 150,00mm / 2.5984" – 5.9055"
(HSS-E with the latest AlTiN PVD coating). Economic and wear-resistant cutting insert with positive geometry and excellent chip control feature. Insert geometry with constant cutting angle, chip splitters and corner protection. First choice for machining steel, cast iron, nodular cast iron and nonferrous metals.

Geometry HR Grade SP4036
Diameter range 10mm - 25mm / 0.390" – 1.000"
(Micrograin carbide with TiAlN PVD coating). First choice for machining low hardness steel (<230 HB) and stainless steels. This geometry has a helically ground point, a strengthened cutting edge and radial land allowing for excellent centering and high penetration rates.

Geometry PR Grade H22
Diameter range 10mm - 25mm / 0.390" – 1.000"
(Micrograin carbide). First choice for machining aluminum and other non–ferrous alloys. This geometry has a cross point grind, wide chip groove, high positive web grind, chip splitters and no radial land. This allows for high penetration rates and smooth evacuation of the machined chip.

Geometry SR Grade SP4036
Diameter range 10mm - 35mm / 0.390" - 1.375"
(Micrograin carbide with TiAlN PVD coating). First choice for machining steels, cast irons and nodular irons. This geometry has a cross ground point, radial land and a corner protection chamfer.
