NeXgen Block Leg Reamers

Available with Smith Gemini MT or TCI Cutters

One Piece Integral Center Section - Manufactured from a single piece of A36 plate steel to allow for maximum structural integrity. Additional benefits to the one piece center section include longer tool life and improved repairability when compared to a standard weld assembled hole opener body.

Improved Hydraulic Flow - The NeXgen reamer body is designed with maximum junk slot clearance to enhance cuttings removal. This increases flow area, reduces body and cutter wear and increases rate of penetration.

Replaceable Smith Gemini TCI or MT Cutter Segments - Featuring specially designed block leg segments with twin sealing surfaces, sealed precision roller bearings and wear resistant binary carbide gauge inserts. This provides substantial durability and allows longer cutter runs.

Built in Front Centralization - Hard facing is standard on all stabilizer rings & gussets to decrease pilot guide wear.
