MASTER OF VERSATILITY
Expectations are high and innovation is an obligation at the very top. It is a claim we take very seriously.

The new ALPEN Sprint Master will show you new dimensions of speed and reliability. It reduces drilling time by around a third thanks to optimized drill geometry and the special ALPEN tip shape. And still delivers the customary top-quality result.

Satisfaction is guaranteed further still by a longer service life that has been increased by a factor of 3 through the use of high-quality HSS steel and a special heat treatment process. The speed and long-term efficiency of a champion are words that best sum up our ALPEN Sprint Master.

Range of application:

HSS twist drill: toughness and precision combined with excellent cutting efficiency for drilling alloyed carbon and plain steel. Ideal for hand held operations.

Strengths

  • 30% faster
  • 3 times longer service life
  • Sharp cutting edges even with larger diameters little feed pressure is required
  • Very high elasticity and greatest toughness with optimum cutting performance
  • High fracture resistance even with smaller diameters low risk of breakage due to high elasticity
  • Optimum drilling performance even in unfavourable working conditions

Alpen drill bits are manufactured in Austria.

REALLY CUTE SHOE BUT CUT WAY TOO SMALL!
Size: 8, Color: Black Patent
I received the black patent leather shoes today and they are so cute! Sadly I need to return them because they are cut way too small. I normally wear a 7.5 or 8 on dress shoes so I ordered the 8. They are so tight across the top that it's uncomfortable as soon as I put them on. They are smaller than a normal size 8 dress shoe. The big toe area is extremely uncomfortable because it doesn't allow any room for it at all, so my big toe just presses against the side and end of the shoe without even walking in them. I have very narrow feet and these still are too small for me. So I am returning them and I already ordered a 8.5 W and hope that will fit much better. The patent leather is very cute and adds just enough dressy that I can wear them with slacks or my Capri jeans. I like the slip on and the cushion foot bed because it feels soft.

Love these flats!
Size: 9 Wide, Color: Black White Faux Snake Skin, Size: 9 Wide, Color: Black White Faux Snake Skin
One of my favorite pair of flats! I’ve had these for several years and they are still comfortable, in good shape and really add a little spice to my outfits. I can wear these all day and not have any foot pain or discomfort as a result. The quality is good, fit is perfect and I tend to have difficulty with shoes due to bunions. Love these!!
