Product Details
Four Types, Four Ground Conditions
A reamer that suits ordinary soil will not suit hard ground, and the wrong one costs you a pass. KISN supplies four structural types so the tool can be matched to what the bore actually crosses.
Extrusion Reamer
High-quality steel for ordinary soil layers. Low working resistance and good hole-forming performance.
Flow-Channel Reamer
One-piece cast body with thick walls, for hard soil layers. High wear resistance and long service life.
Cutting Reamer
Strong passability, for clay and backfill layers. Fast operation.
Shield Reamer
For shield tunnelling conditions, customised per project.
Choosing Between Them
Tell us the soil condition and the reaming diameter and we will recommend the type. Where a job crosses more than one formation, customers often order two types and change over mid-bore.
Where It Ships
Supplied to contractors in Africa, Southeast Asia and the Middle East.

Frequently Asked Questions
Which reamer should I use?
It depends on the ground. Extrusion reamers suit ordinary soil; flow-channel reamers suit hard soil; cutting reamers suit clay and backfill; shield reamers suit shield tunnelling conditions.
Can I mix types on one job?
Yes. Where a bore crosses more than one formation, contractors often run two types and change over.
Are reamers available in custom diameters?
Tell us the reaming diameter and ground conditions and we will confirm what can be made.
What is the minimum order and lead time?
Standard minimum order is 10 pieces, with a lead time of 10 days. Special specifications are made to order.
