Kiaat (Pterocarpus angolensis) – CNC Router carving test
Kiaat wood carved with clear cutting lines and retains relief detail during the CNC router test. Test was run on two relief with 1/4′ router bits. The rotation speed versus feed rate is not critical. The wood produced a clear surface with good developed shavings. Throughout the carving process the relief remain clear of any burs. The wood has interesting colouring that can be utilise as part of the design.

Distribution: South-central Africa
Other Names: Muninga, Kiaat, Mukwa, Morôtô, Umvangazi, Mubvamaropa, African Teak or Wild Teak
Characteristics: The heartwood colouring is highly variable, pale uniform brown, golden brown, chocolate brown, brick-red or purplish brown with darker or redder streaks. Texture is medium to coarse, and the grain runs straight to interlocked. Sapwood is quite wide, especially on older trees and is oatmeal in colour.
Working Qualities: This timber has a medium bending strength, high crushing strength, low resistance to shock loads and very low stiffness. Works well with hand and machine tools, but there is a moderate blunting effect on cutting edges. It glues well and can be stained and polished to a very good finish.
Uses: Kiaat is used for furniture, panelling and high-class joinery and domestic flooring.
