Check the material type, thickness, and hardness. Review the screw spec sheet for recommended tip angle and flute design. Match the drill point tip to those parameters. When in doubt, test on scrap material to confirm it cuts a proper pilot hole without excessive force.
Each tip design handles a range of thicknesses. Manufacturers list the maximum metal thickness for a given tip angle and flute. For example, some tips cut through up to 3 mm steel; others handle thicker gauges. Always verify specs before use.
Drill point tips suit metal; they may overcut or split softer materials. For wood or plastic, choose a self-tapping screw with a pointed tip designed for those substrates. If you must use self-drilling screws in thin plastic, test carefully and consider pre-drilling to avoid damage.
