Solving tapping challenges with smart tooling
In the world of precision manufacturing, the smallest of inefficiencies can create costly production roadblocks. For PT Sparta Guna Sentosa, an Indonesian automotive and industrial components manufacturer, one roadblock came in the form of persistent long chips during tapping operations — an issue that had long affected production efficiency and tool reliability. But through collaboration and the application of advanced solutions from metal cutting and manufacturing solutions manufacturer Sandvik Coromant, solving that challenge has unlocked new levels of productivity, cost savings and opportunity. Founded in 1986 in Bandung, Indonesia, PT Sparta Guna Sentosa started out servicing and manufacturing components for the textile industry. As of 2025, it manufactures a broad range of high-quality mechanical parts, such as pins, bushes and shafts for diverse industrial applications. Backed by advanced automation and machining capabilities, Sparta Guna Sentosa has positioned itself as quality-driven supplier. However, even the most well-equipped production lines can face technical challenges. Understanding the problem For years, the company struggled with long chip formation during tapping, a common but significant machining challenge. This issue led to several complications, including frequent machine downtime caused by chip jamming. As a result, scrap rates and rework increased, tool life became unpredictable and the risk of breakage rose. These problems compounded rather than occurred in isolation — worn tools accelerated chip buildup, requiring repeated spindle cleaning and further halting production. Despite multiple attempts to address the root cause, the company struggled to find a consistent and effective solution. Partnership that drives productivity Having already built a strong relationship with Sandvik Coromant through regular use of its drills and inserts, PT Sparta Guna Sentosa turned to the metal cutting expert for help resolving these tapping issues. Sandvik Coromant stepped in and proposed a live five-day trial using its CoroTap DT100-PM104DA-M8P1PL taps, featuring innovative chip-breaking geometry. […]
