Abstract
A downhole tool, comprising: a mandrel having first and second opposing ends and an outer mounting surface, the first end comprising a male threaded portion; a tool component mountable on the mounting surface by sliding said tool component onto the mounting surface from the first end of the mandrel; and a load sleeve defining a torque shoulder, wherein the load sleeve is mountable on the mandrel and securable adjacent the male threaded portion of the first end of the mandrel such that the torque shoulder and the male threaded portion define a pin connector to facilitate connection with a box connector of a separate component.

Abstract
A wellbore roller-reamer comprises a mandrel rotatable about a mandrel axis, and a first roller mounted around the mandrel and having an outer reaming surface for engaging a wall of a wellbore. The first roller is rotatable relative to the mandrel about a first roller axis which is offset from the mandrel axis such that, during use, rotation of the mandrel with the outer reaming surface engaged with a wall of the wellbore causes the first roller to be driven to rotate relative to the mandrel and ream the wall of the wellbore.
IPC Classes ?
- E21B 10/30 - Longitudinal axis roller reamers, e.g. reamer stabilisers
- E21B 10/22 - Roller bits - characterised by bearing, lubrication or sealing details
