Abstract

A drill holder (100) comprises: a base (108); an elongate support member (110) extending substantially perpendicularly from the base (108); and an arm (112) mounted to the support member (110); wherein the arm (112) extends substantially perpendicularly from the support member (110); the arm (112) is free to slide along at least a portion of the support member (110); and the arm (112) comprises: holding means (126) for holding a drill (102); and a weight (124).

Description

technical field [0001] The present invention relates to a drill holder for holding a drill including but not limited to a rotary percussion drill for drilling into stone, concrete, brick or mortar. Background technique [0002] Drilling rigs such as rotary percussion drills or rotary hammer drills are used to drill into stone, concrete, brick or mortar. This type of drill provides a hammering action to move the bit in and out while the bit rotates. [0003] Using such drills exposes the worker to arm vibrations, which can lead to, for example, arm vibration syndrome and carpal tunnel syndrome. Contents of the invention [0004] In a first aspect, the present invention provides a drill holder comprising a base, an elongate support member and an arm, the elongate support member extending substantially perpendicularly from the base; to the support member. The arm extends substantially perpendicularly from the support member. The arm is free to slide along at least a porti...
