JUNK MILLS   Download PDF Information sheet

Drillstar Junk Mills are designed for heavy-duty milling jobs. The fruit of over 20 years of experience in design and hardfacing, they are available in five standard designs covering a wide range of milling applications :

Conventional Junk Mill: designed for cement, general junk, tubing milling or packer removal.
Flat Bottom Junk Mill: with more hardfacing for a longer tool life.
Conebuster Junk Mill : its concave shape is ideal for milling bit cones and other objects by keeping them centered under the mill.
Integral Bladed Junk Mill : this uncompromising mill is ideal for cement milling jobs, plug removal or general milling jobs. Tool integrity is ensured by integral blades machined out of the body, which can be fitted with TOPMILL cutting inserts for improved ROP.
Super Junk Mill : designed for intensive use, such as drill collar milling. Its wide blades allow for maximum weight to be put on the mill.

All Drillstar mills feature integral AISI4145H body and can be used in both cased and open hole. They are available in a variety of standard and custom sizes, with or without stabilizing blades
