M3-M10 HSS tap drill set

The Mesee ME24US-0687GY contains six combination bits covering thread sizes M3 through M10 with pitches from .5 to 1.5. Each piece is made from high-speed steel with a blue coating for hardness and wear resistance. The 1/4-inch hex shank fits cordless drills, electric screwdrivers and bench drills for quick changes. The set arrives in a 16 pack plastic case weighing 75 grams.

Single-pass drilling and tapping

Each bit drills, taps, deburrs and countersinks in one operation without swapping tools. A self-centering point eliminates the need for centre punching at a 90 degree angle. The back-tapered design prevents thread damage from over-drilling. Applying cutting oil increases working speed and extends bit life when used on plastic, wood, fibreboard or soft metals such as copper, brass and aluminium.

Compact storage for mobile work

The plastic case organises all six sizes with engraved markings for fast selection. Hex shank compatibility spans cordless drills, electric screwdrivers and bench machines without additional adapters. The 21 degree collation angle keeps bits secure during transport. This set suits DIY repairs, home maintenance and small projects where changing separate drill and tap tools would slow the workflow.

Questions about this item

How do I install the 1/4-inch hex shank bits in my cordless drill?

Insert the hex shank fully into the chuck until it locks; the anti-slip design prevents rotation. The step people miss is failing to seat the shank completely, which causes wobble and damaged threads.

What maintenance will the HSS blue-coated bits need over time?

Apply cutting oil during each use to reduce wear and heat. After use, wipe chips off the spiral flutes and store in the supplied case to protect the coating from moisture and impact.

What limit appears first when tapping M10×1.5 in aluminium under sustained use?

Heat buildup at the cutting edges dulls the HSS fastest; the blue coating delays wear but continuous drilling without oil or cooling will degrade the tap threads before the shank or case shows any issue.
