GBC Shredmaster GLM11 Micro Cut Paper Shredder Review

Shredders are a vital part of many offices today.  One great machine for large departments is the GBC Shredmaster GLM11.  This device matches automatic functions, decent capacities, and high security for an easy to use, convenient machine.  Durable design allows this machine to stand up to the heavy shredding needed by an office with more than ten people.  Here is a closer look at the strengths and weaknesses of the GLM11.


  • Automatic features greatly contribute to the simple operation.  Inserted materials are detected in the feed and shred on cue.  When they’ve finished, the blades shut down automatically.  If a jam occurs, the auto reverse helps to clear it by sending the clogged material back out to the user.    Optical signals on a lit display panel keep the user constantly updated on the machine’s status.  After two minutes of no use, the engine quiets down to a energy conserving mode to save electricity.
  • The powerful motor is rated for continuous duty.  This means is can shred all day without needing frequent cool down periods.
  • As many as 11 stapled or paperclipped sheets can enter the nine inch feed opening at once.  The blades can also handle credit cards, CDs, and DVDs.  Materials are shred at a respectable rate of 18 feet per minute, quickly rendering all your documents unreadable.
  • The micro cutting mechanism takes full size paperwork and turns it into small particles only 3/32″ by 19/32″ in size.  These tiny pieces earn a level four security rating.  At this level, all your financial, medical, and personal information stays safe.
  • Shredding remnants fall into a voluminous 30 gallon waste bin.  You have a choice of plastic or environmentally friendly paper shred bags.  The container is housed in a cabinet for easy removal and replacement when the bags are full.
  • GBC offers one of the best warranties in the business.  This model has two year coverage including on-site service.  The cutters carry an impressive 20 year guarantee.


  • The lower capacities seen on this machine are fairly typical of high security machines.  Generally, higher security equals lower capacity and speed.  If your needs are more for quantity rather than high security, we recommend the GLX3055.
  • Unlike many other GBC shredders, this one isn’t equipped with Jam Free technology.  As long as you don’t overload the blades, you shouldn’t have much of a problem with jams.
  • At 156 pounds, this is one heavy machine.  Unfortunately, there aren’t casters on the bottom to add mobility.  We suggest using a dolly if you need to move it around.

The GBC Shredmaster GLM11 is definitely able to handle the high security needs of a medium to large office.  Automatic features provide ease of use while the micro cutting blades dice up all your private information and keep your identity safe.  When you add on an impressive warranty backing, this is one machine you won’t regret investing in.  We think the GLM11 is an excellent choice for your next office shredder.
