What type of wood is specified for the mallet head?

Timbers such as Babul, Haldu, Sissoo, or Anjan are specified due to their hardness and shock-resisting properties (Clause 3.1).

What is the requirement for the handle material?

The handle must be made from sound, straight male bamboo (Dendrocalamus strictus) and be free from cracks, knots, and insect attack (Clause 3.2).

Practical Notes

The standard emphasizes that the grain of the wood for the head must run parallel to the axis of the handle to prevent splitting during use.

Selection of appropriate timber (e.g., Babul for head, Bamboo for handle) is crucial for the tool's shock resistance and service life.

This standard is primarily used by manufacturers for quality control and by purchasers for procurement specifications.
