The reverse circulation junk basket type LL is designed to remove small pieces of junk such as bit cones, hand tools, slips, etc from the bottom of well. It's unique feature is utilizing the principle of reverse fluid circulation.

Bowen Type Series 150 Releasing & Circulating Overshot is an external catch fishing tool designed to retrieve tubular items from the well bore. It is rugged, economical, and easy to use. Overshoots come with a wide range of available accessories. These fishing tools have proven to be the most versatile and reliable in the field.

Bit breaker baskets are used to assist in pipe/bit separation. Available bit size: 3.3/4, 4.1/8, 4.3/4, 5.7/8, 6-6.1/8, 6.1/2, 7, 8.1/4, 8.3/4, 9, 9.1/2-9.5/8, 9.7/8, 12.1 /4, 13.3/8, 13.3/4, 14.3/4, 15.1/2, 16, 17, 18, 17.1/2, 20, 20.1/2, 24, 26.

​

The rotary reamer is designed for every reaming operation but particularly for stabilization purposes when drilling in very abrasive formations. This is a versatile tool. It will fit hole sizes ranging from 4-5/8" to 26".

BZ Fixed Diameters hole openers are made of tough treaded allow steel for maximum strength. Cutter arms are hard faced and welded on body, equipped with removable cutters. Cutters are available in three types.

Integral Spiral Stabilizer is a one-piece tool made by AISI 4145H alloy steel and fully heat-treated to 285-341 Brinel Hardness number, and 54 Joules of minimum impact value. Three spiral blades have been designed to minimize the downhole torque, to reduce damage of the hole wall, and ensure the maximum fluid circulation. When drilling vertical holes, they shall be applied to reduce drift of drill bits and keep the drill bit straight downward.

It's made from ANSI 4145H chrome-molybdenum steel. The content of microelement is effectively controlled.

​This Float Valve is normally installed in a standard bore-back of the bit sub, to provide fluid flow control at the bottom of the drill stem. It also prevents backflow of cuttings from plugging the drill bit jets while making connections.
