Countersink drill bit HSS 4 mm

The Wovar countersink drill bit 4 mm provides a beautiful finish to your decking. Countersinks are also called milling drills. This milling drill creates a depression in which the head of our stainless steel 410 decking screws plunge exactly. The shank diameter of the countersink drill bit is 4 mm and the milling diameter 12.4 mm. The countersink bit 4 mm is made of high strength steel (HSS). The terrace screws sink nicely into smooth decking boards, partly due to the 3 razor-sharp cutting edges. The cutting edges ensure a burr-free depression in your wood. This makes the countersink drill perfect for milling the screw head with our decking screws.

Working with the 4 mm countersink bit from Wovar is very easy. First you determine where the screw should be installed. Then hold the countersink upright against the wood where the screw should go. Drill 4 seconds and you have the right depth for a nice countersink of our Wovar decking screws.
