20mm square hole drill bits for wood in steel with bearings, milling cutter for square drilling.

Discover our high-quality square hole drill bit, designed for exceptional performance and durability. With a 20 mm diameter and weighing approximately 363 g, this bit is forged from bearing steel and has undergone complete heat treatment, guaranteeing very high hardness and a long service life. Its design incorporates long, efficient U-shaped chip ejections, facilitating the removal of wood chips and thus significantly improving drilling efficiency. A drill sleeve protects the tool by distributing force over a plane, effectively preventing any risk of cracking at the start of use. The universally shaped shank and the circularly designed bit tip ensure extremely stable clamping in the machine. This tool is perfectly suited for drilling through density board (particleboard), MDF (medium-density fiberboard), particleboard, solid wood, and other wood-based products. It is specifically designed for use on a square hole drill or a square tenoning machine. You will receive a brand new square hole drill bit in its original condition.
