In the new brochure is the assortment of Precision Twist Drill threaded shank drills, which was recently expanded in 2018 and are suitable for machining general to medium duty, low tensile strength materials in confined areas. Also, Precision Twist Drill aircraft extension drills, manufactured to provide long life and high levels of productivity. This assortment includes a highly efficient flute design and a 135° NAS split point, which reduces thrust forces and improves positional accuracy when hand drilling.  

Specific Wetmore branded items in the brochure include countersink drills for use in Nutplate drill motors and tapered reamers for hand drilling (through bushes) or with controlled speed/feed drill motors. Dagger drills - designed to produce delamination free holes; double margin step drills to machine close tolerance holes; piloted countersinks for use on pre-drilled holes in aluminum, graphite and fiberglass; as well as carbide routers to machine the edges of composite panels made from Carbon Fibre Reinforced Polymer (CFRP), fiberglass and Kevlar.
