Product Number: AK4749
Drilling multiple hole sizes with standard bits means constant tool changes, clogged flutes, and imprecise results. The Sealey AK4749 HSS 4341 Spiral Flute Step Drill Bit Set solves this with three high-speed steel bits covering 18 different hole sizes from a single set. Made from HSS 4341 steel, the spiral flutes actively clear swarf during drilling, keeping the cutting path clean and delivering clog-free, precision results without the need to swap bits repeatedly. Size #1 covers 4-12mm, Size #2 covers 4-22mm in 2mm increments, and Size #3 covers 4-30mm in 2mm increments. The set is supplied in a storage case to keep all three bits protected and organised between uses.
