Cobalt Drill Bit Set 5.5mm 10pc HSS 5% Co Twist Drills for Metal

A 10-piece drill bit set of matching 5.5mm HSS twist drills with 5% cobalt, supplied as a practical spare pack for regular use. Useful when you need the same drill size more than once in a day, this cobalt HSS drill bit set gives you a consistent stock of replacement bits ready to hand.

Used across workshop jobs, garage work, site boxes and home maintenance, these bits suit anyone carrying out repeated drilling where mixed sets are less convenient. They are handy for trade use, DIY repairs and general servicing when a 5.5mm hole size comes up regularly and you want matching spares ready in different tool cases or on the bench.

The pack contains 10 twist drills, all in the same 5.5mm size, which makes it easier to stay organised when one bit is already fitted in a drill or another needs replacing. The HSS construction with 5% cobalt is intended for ongoing drilling work where a standard bit may not last as well in repeated use. Keeping a spare pack of one common size close at hand can save time searching through mixed drill assortments and helps avoid work being held up by worn or missing bits. For regular drilling and replacement stock, it is a straightforward way to keep common consumables where you need them.
