A knock hole die gun reamer that does not affect roundness, surface accuracy, or inner diameter even with a slit hole.
The "ND-OS-GRS/ND-OS-GRL" is a knock hole diamond gun reamer with oil holes, suitable for achieving optimal precision in processing knock holes, slit holes, and cross holes. It ensures roundness of less than 5μm and surface accuracy of less than Ra0.4μm. Even with slit holes, there is no impact on roundness, surface accuracy, or inner diameter. Additionally, it suppresses inner diameter variation in intermittent holes. We offer a short type (GRS) and a long type (GRL). 【Features】 ■ Ideal for processing knock holes, slit holes, and cross holes ■ Available for processing hole accuracy requirements IT grades H7 and H8 ■ Internal lubrication (GRL) ■ Effects of carbide guide pads: - Improved straightness (countermeasures for hole bending) - Enhanced surface accuracy - Suppression of inner diameter variation in intermittent holes *For more details, please refer to the PDF document or feel free to contact us.
