Alpha Onsite+ Step Tip Drill & Tap Sets (SM7DTST / SM17DTST)
The Alpha Onsite+ "Step Tip" range revolutionizes drilling and tapping by solving the most common frustration with combination bits: jamming. Featuring a patented stepped tip geometry, these bits drill, tap, and deburr in a single pass up to 6x faster than standard HSS equivalents. The unique tip design eliminates the need for pre-drilling and prevents the tool from binding in the hole, ensuring smooth operation even in tough materials like stainless steel. Available as a dedicated Drill/Tap set or a comprehensive Workshop Kit.
Features:
Patented Step Tip Technology: The stepped tip design allows the bit to self-start instantly without "walking" and drastically reduces the torque required, preventing the jamming and snapping often associated with standard combination taps.
6x Faster Performance: Tested to work up to 6 times faster than standard HSS bits, allowing you to drill and tap threads in seconds—ideal for high-volume onsite installations.
AlTiN Coating: Coated with Aluminium Titanium Nitride to provide extreme heat resistance and surface hardness, significantly extending the service life of the cutting edges when working with stainless steel.
Impact Driver Ready: All bits feature a 1/4" Quick-Change hex shank that locks securely into impact drivers and cordless drills, ensuring zero slip under high torque loads.
Versatile Material Application: Engineered to cut clean, precise threads in mild steel, stainless steel, aluminium, and non-ferrous metals without the need for a pilot hole.
