Reamer bits KRp-2CT
Reamer bits are designed for calibrating and reaming well sections represented by medium, hard and abrasive formations. Reamer bits allow reaming horizontal and high dogleg severity wells preventing accidental sidetracking and sizing wellbore to nominal diameter both moving down and up.
Reamer bits are produced with two tapered surfaces. Tapered surfaces, reinforced with tungsten carbide inserts with cutting edge, comprise reaming part of a tool.
|Reamer bit type||OD, mm||Default quantity of blades||Tool joint|
|120,6||Z-76 / Z-86||2 ⅞ Reg / NC-31|
|210-218||Z-133 / 147||NC-50 / 5 ½ FH|
Spiral eccentric reamer-bits
Designed for calibrating and reaming well sections represented by soft and medium rocks, as well as for eliminating the micro tortuosity.
The eccentric shape of the blades of the KRpC-L with PDC cutting structure makes it possible to use the reamer with bits equal to or larger than the nominal diameter of the reamer.
