Reliability

A High Quality Tool Will Last Longer and Have Less Frequent, Less Costly Maintenance

• Last longer before replacement
• Require less costly maintenance
• Require less frequent maintenance
• Parts less costly

If using a similar style of tool, an AIMCO high quality tool should last longer, due to the quality of the components.  Think about a small inexpensive car compared to a compact Mercedes.  Both have a four-cylinder engine, cruise control, power steering and brakes.  What makes the Mercedes better?  It is the quality and workmanship of those individual components.  This also applies to accessories such as bits and sockets, mag-o-nets, and more.

If proposing a different type of tool than what the customer is currently using, the newer tool may last longer.  For example, a quality shut off clutch driver like the AIMCO US-LT driver should last much longer than the typical cushion clutch or positive clutch screwdriver.  Similarly, an AIMCO pulse tool should last many times the life of an impact wrench.

Less frequent or less costly maintenance:  In general, a pulse tool will have much lower maintenance costs than replacing the hard parts of a clutch tool or impact mechanism.

A customer uses an impact wrench which dies every 8 months or so at a cost of $400.  Maintenance during that time is another $150.  The customer is looking at an angle nutrunner with a much higher reliability.  The AIMCO UAN nutrunner ($1,700) should last for over 10 years, with a typical yearly maintenance cost of $100 with a major overhaul after 5 years that costs $800.

OPERATING COST OF IMPACT:
($400 + $150) / 8 months X 12 mo/yr X 10 years = $8,250 is the 10 year operating cost

OPERATING COST OF NUTRUNNER:
$1,700 + ($100/yr X 10 yrs) + $800 = $3,500 is the 10 year operating cost

PAYBACK:
($1,700 - $400) / ($8,250 - $3,500) / 10 years = 2.7 years

This means that the purchase of the UAN nutrunner will pay for itself in 2.7 years!
 

A customer uses cheap sockets on 20 tools that break every two weeks at a cost of $3 each.  He is considering Ergo-Drive sockets that last longer but cost $15 each.  The Ergo-Drive sockets should last for at least 4 months.  They will also increase torque transmission and have less vibration, for ergonomic and quality improvements.

YEARLY REPLACEMENT COST:
20 X $3 X 26 times/year = $1,560 a year to replace standard sockets
20 X $15 X 3 times/year = $900 a year to replace Ergo-Drive sockets

PAYBACK:
$900 / ($1,560 - $900) = 1.36 years or just over 1 year, 4 months

This means that the purchase of the Ergo-Drive sockets will pay for themselves in 1 year, 4 months!
