Based in St. Charles, IL, Shars Tool Company has been a leader in providing customers with premium imports through their commanding e-commerce venues at and beyond. 


  • Aventor IP65 Coolant Proof Micrometers
    Coolant Proof IP65 protection level means the micrometer is dust tight and protected against water jet, coolant and cutting oil but not in an immersed fashion. Available in 1", 2" and 3"....

  • Coolant Proof IP65 protection level means the micrometer is dust tight and protected against water jet. In our laboratory test we would apply water jets under standardize pressure condition for 30 minutes. Designed to work in adverse condition exposed to coolant, water, dust, or oil, even if the caliper is splashed with coolant or water, there is no need to wipe or clean the spindle. Anti-corrosion treatment is required after exposing to water or coolant environment. 

    Carbide tipped measuring face is precision ground and micro lapped to give a mirror finished with 0.3um / 0.000012" flatness. Enhanced grip by integrating cross knurling pattern into the plastic mold on the side and bottom surface of the frame. Spring loaded ratchet mechanism applies constant clicking force to workpiece to ensure repeatable measurement.

  • Tegara CAT40 Tool Holders
    Wide variety of ER Tool Holders, End Mill Holders, Dual Contact holders, etc. to fit all your tool holding needs....

  • We optimize our process for both efficiency and accuracy by utilizing Kawasaki robotic arms to load and unload bar stock into the Mazak multi-tasking machine centers. We use SCM420 alloy steel to lay the foundation and case harden to RC 57-59 with a core of RC 34-39 to provide good core strength and maximize wear life. The core creates a dampening effect which reduces vibration in high speed milling to improve surface finish. The AT3 or better taper accuracy ensures 80% or better taper contact with spindle and using Stotz Air/Electronic Gaging for inspection on the taper. We precision grind the internal bore surface to <.0002" TIR and all bores are ground on a CNC grinder to ensure close run-out tolerance and evenly contact between the collet and the bore pocket. We use Haimer laser balancing machines to deliver a tool that can operate flawlessly at 20000 RPM and Mitutoyo or Mahr indicators to check the run out.

    The maximum torque is laser marked on the ER collet nut face to take the guess game out of the way to ensure proper amount of force should be applied while tightening. Innovative coating process significantly increases the clamping force by 75% compared to standard ER collet nut. More gripping force provides better rigidity and reduces the possibility of losing grip on the round shank which lead to expensive damage on cutting tools and work piece material.
