Series 65 Jet Nozzle Assembly – (Alloy Steel)


The Series 65 Jet Nozzle Assembly is a four-part assembly, comprising of  a weld on socket, tungsten carbide jet nozzle, threaded nozzle retaining jacket and O-ring seal. These assemblies are an essential to companies designing and fabricating in-hole tools, as well as a key part of any drilling contractors’ on-site inventory, which can be quickly incorporated into on-site tooling when unexpected conditions are encountered. The assembly can be ordered in nozzles sizes ranging from #08-18 Part No. JNAS65A-XX  (08 | 09 | 10 | 12 | 14 | 16 | 18).

Jet Nozzle Assembly – Series 65  (Alloy Steel – A1045)


High-pressure carbide jet nozzle assembly (A-513 alloy)

High-pressure carbide jet nozzle assembly

The series 65 jet nozzle assembly comprises of a four part assembly, comprising of a weld on socket, tungsten carbide jet nozzle, threaded nozzle retaining jacket and O-ring seal. This assembly is ideal when building tools where high presser fluid is used to aid in the cutting (hole opening) by flushing the cutting away from the cutting surface, thus extending the life of the cutters and/or aiding in the cutting of softer formations by hydraulically removing the formation. High pressure flow across the cutting surface increases ROP (rate of penetration) as well as increasing the life of the cutters. By efficiently removing the cuttings away from the leading edge of the cutter it insurers that cuttings are not being re-cut or act as an abrasives which will shorten the life of any cutter. The socket weldment can be ordered in two materials, C1045 Alloy Steel and 316 Stainless Steel. The alloy part No. JNAS65AXX (08 | 09 | 10 | 12 | 14 | 16 | 18). The last 2 digits (XX) denotes nozzle size.

Failsafe Nozzle Tool

A redesign of the Smith slotted extraction tool has virtually eliminated the problems associated with the design, i.e stripping of the tool and/or retainer slots.

Our retainer design uses a standard 1/2″ (S65) or 3/8″ (S45) socket/breaker bar for removing retainers and nozzles. This improved design eliminating the downtime resulting from damaged tools and/or nozzle slots.

Where drop in sockets cannot be used do to design or space constates i.e. well servicing tool etc., necessitating that the nozzle receptacle be machined directly into the tool body, HDDJETNOZZLE offers users the following “Thread-Bore Machine Detail”.

It should be noted the thread-bore details are shown  “WITHOUT LEADING COUNTERSINK” & “WITH LEADING COUNTERSINK” leading face.  Where space permits, we recommend WITH LEADING COUNTERSINK as it helps protect the lead-in thread and Retainer face.



AISI 1045 Material/Welding Notes

Physical Characteristics

AISI 1045 is widely used for all industrial applications requiring more wear-resistance and strength…

AISI 1045 steel is a medium tensile steel supplied in a black hot-rolled or normalized condition. It has a tensile strength of 570 – 700 MPa and Brinell hardness ranging between 170 and 210. (AZO MATERIALS)

Welding AISI 1045 Medium Carbon Steel

AISI 1045 steel is characterized by “good weld-ability”. Best results will be achieved by Pre-heating the sockets before full welding, with optional Stress-releasing after welding.

Certain facts about welding of AISI 1045 steel are:

  • AISI 1045 steel is readily welded when correct procedure is followed.
  • Welding AISI 1045 steel in through-hardened, tempered and flame or induction hardened condition is not recommended.
  • Low hydrogen electrodes are preferred for welding AISI 1045 steel.
  • The workpiece is
    • Pre-heated at 200°C–300°C (392°F – 572°F)
    • Maintained at the same temperature during welding
    • Cooled slowly using sand, ashes etc and
    • Stress relieved at 550°C – 660°C (1022°F – 1220°F).

Referenced below are links and excerpts from two widely recognized welding authorities for your quick reference. In addition to these, there are many others covering this topic throughout the internet as well as your local welding supply.

When in doubt, consult with a trusted welding distributor for advice on the process. Doing so can help ensure the durability — and the cost-savings — sought in an application featuring both stainless steel and carbon steel.

INTERLLOY PTY LTD – 1045 Medium Tensile Carbon Steel Bar

“1045 is a medium tensile low hardenability carbon steel generally supplied in the black hot rolled or occasionally in the normalised condition, with a typical tensile strength range 570 – 700 Mpa and Brinell hardness range 170 – 210 in either condition.Characterised by fairly good strength and impact properties, plus good machinability and reasonable weldability in the hot rolled or normalised condition.”


AZO MATERIALS – AISI 1045 Medium Carbon Steel

“AISI 1045 steel is a medium tensile steel supplied in a black hot-rolled or normalized condition. It has a tensile strength of 570 – 700 MPa and Brinell hardness ranging between 170 and 210. 

AISI 1045 steel is characterized by good weldability, good machinability, and high strength and impact properties in either the normalized or hot-rolled condition. 

AISI 1045 steel has a low through-hardening capability with only sections of around 60 mm in size being recommended as suitable for tempering and through-hardening. However, it can be efficiently flame- or induction-hardened in the normalized or hot rolled condition to obtain surface hardnesses in the range of Rc 54 – Rc 60 based on factors such as section size, type of set up, quenching medium used etc.”
