Mix and match ends across Ditch Witch, Vermeer, API and more — whatever the job needs on each side.
HDD Gear supplies everything around the bore — drill pipe, backreamers and tooling, custom subs, drilling fluids and locating systems — matched to Ditch Witch, Vermeer and TT Technologies machines. Documented specifications and fast delivery, for every rig.
Find your pipe by machine brand — Vermeer, TT Technologies or Ditch Witch — or go straight to our maxi pipes and Hunting pipes. Each page has the full specifications.
IEU-forged drill pipe for the Vermeer Navigator range — from the compact D7x11 to the high-torque D100x120 maxi rig.
View Vermeer pipe→IEU-forged drill pipe for TT Technologies Grundodrill machines, covering the 4X through the 18N–28N range.
View TT Technologies pipe→Drill pipe for the full Ditch Witch line-up — JT Power Pipe for the JT5 to AT100, plus dual-rod AT pipe for All Terrain rigs.
View Ditch Witch pipe→Maxi HDD drill rod for large-bore and maxi rigs — one-piece IEU-forged and friction-welded, S135 grade, with NC50, IF and FH connections.
View Maxi pipe→One-piece forged drill pipe from Hunting — HIWS1, HXT and Ditch Witch-thread — plus the welded Advantage Series.
View Hunting pipe→A dual-rod sonde housing with no grease, no seals and no lid bolts. Mud-lube bearings, a 6-tab LockingLid and room for Subsite, DCI and Underground Magnetics beacons — rebuilt at the rig with a bearing swap.

RocKnife housings for the AT30, AT32, AT40, AT60 and AT100 — one housing family and one rebuild routine for the whole AT line.
View AT housings→Complete housings for the D23x30DR and D40x55DR, or an extension kit that takes an RK30 or RK60 onto the Vermeer rig.
View DR housings→Bearing sets, mandrels, transmitter covers and wear pads for every RK model, listed by part number.
View rebuild parts→Our backreamer range covers everything from soft soils and mud-mixing duty to hard rock. Pick a reamer type to see the full range and part numbers.
One-piece compact reamer with a built-in swivel and tungsten-carbide teeth — versatile from soft ground to tough bores.
View Compact reamer→Our flagship mud-mixing reamer — carbide claws, a nozzle system and a stabilizing ring for long, smooth runs.
View Flycutter reamer→Solid one-piece rock reamer, heavily armed with tungsten-carbide teeth for the hardest ground.
View Kodiak reamer→Open-wing mud mixer — no stabilizing ring for maximum mud flow and mixing where circulation is critical.
View Shredder reamer→Built for soft rock — a large stabilizing area plus replaceable carbide teeth and an integrated swivel.
View Badger reamer→Pulling heads, swivels, housings and bits — the tools around the pipe and the reamer. Pick a category to see sizes and part numbers.

Clamp-in pulling heads with or without cap, and welding heads — for pipe from 25 to 355 mm.
View pulling heads→Ball-bearing pulling swivels that keep the product pipe from rotating with the reamer.
View swivels→Transmitter housings that protect the sonde and hold it straight behind the bit.
View housings→
Tricone rock bits from 5½″ to 6¾″ in IADC 217 to 837, and a 7⅞″ PDC bit — all with API Reg pin connections.
View drill bits→Polymer drilling fluids and additives from ProAction Fluids, from sticky clay to sand, gravel and rock. Six products that work together — start from one base fluid and add what the ground calls for.

A one-product drilling fluid: no recipe and no other additives needed. Best suited to sand and rocky soil.
View drilling fluids→
Multi-polymer blend that builds viscosity and binds clay and other low-density solids, so the cuttings leave the bore cleanly. The base of the ProBore series.
View drilling fluids→
The water-based version of ProDrill, with no oil or hydrocarbons — for jobs where oil-based carrier fluids are not allowed.
View drilling fluids→
Non-foaming detergent that softens hard water and keeps sticky clay from clinging to the bit, the rods and the tooling.
View drilling fluids→
Clay inhibitor that stops reactive clays from swelling and grabbing the pipe and the tooling.
View drilling fluids→
Liquid multi-polymer blend for dense, permeable ground from sand to rock: disperses quickly, carries coarse cuttings out and seals the bore wall.
View drilling fluids→When it isn't on the shelf, combine any two ends into one purpose-built sub — set the overall length and send it to us for a fast quote.
Mix and match ends across Ditch Witch, Vermeer, API and more — whatever the job needs on each side.
Set the overall length in millimetres and watch a live drawing update as you build.
S135-grade steel and a guaranteed thread fit, with same-day production on many builds.
Not sure which end connection you have? We'll help you identify it.
Every drill pipe and backreamer is built from certified alloy steel — armed with tungsten-carbide cutters where the ground turns hard. The ratings and dimensions you need are published for every part number.
Drill-pipe tool joints and reamer connections are machined to the exact thread of every Ditch Witch, Vermeer and TT Technologies rig — IF and Reg, pin to box — so every tool is a true drop-in fit.
We keep a broad inventory of drill pipe, tooling and drilling fluids, so standard orders ship fast — with express freight available when the job can't wait.
