Indexable gun drill
The diameter of these drills ranges from 11.52mm to 65.00mm. Only 5 blade sizes can cover the entire range.
The inserts can be directly installed and can produce large-sized holes without adjustment.
The drills are fixed on the guide plate using screws
The indexable gun drills have processing advantages that traditional gun drills cannot match, such as good chip breaking effect, high feed rate, and convenient tool replacement. However, the tolerance range of machining aperture is too large, the effect of overcoming cross gaps is poor, and the high requirement for machine tool stability leads to its poor universality. Generally used in areas with low requirements such as blind holes, tube plates, and bar material holes
三角形刀片具有3个切削刃。 正前角排屑器和排屑槽的几何形状允许使用的进给速度是传统枪钻的进给速度的3至4倍。 它们由微粉碳化物制成，并具有多种PVD耐磨涂层。
Suitable for lathes, machining centers, and deep hole machining machines.
Efficient chip formation through specially developed tip geometries
Reduce downtime caused by rapid replacement of worn parts
Easy to use, no need for sharpening, no need to adjust length, inventory of vulnerable parts.
Extended tool life through full coating, edge treatment, and indexable design
Due to the availability of vulnerable parts and the most common sizes, it can be quickly provided.
The triangular blade has three cutting edges. The geometric shape of the front corner chip conveyor and chip groove allows for a feed speed of 3 to 4 times that of traditional gun drills. They are made of micro powder carbides and have various PVD wear-resistant coatings.
医疗器械，汽车燃料系统，玻璃工业和许多其他应用都可以通过使用整体硬质合金长笛钻在很小的孔上钻孔而受益。 管状结构枪钻的尖端没有钎焊接头，从而提供了更高的强度，从而提供了更好的穿透率和工具寿命。 然而，如此小直径的枪钻要求遵循特定的操作参数以确保成功。 我们很高兴提供专家级的应用工程来实现这一目标。
Gun drilling application field:
Medical devices, automotive fuel systems, glass industry, and many other applications can benefit from drilling small holes using integral hard alloy flute drills. The tip of the tubular gun drill does not have a brazed joint, providing higher strength and better penetration rate and tool life. However, such a small diameter gun drill requires following specific operating parameters to ensure success. We are pleased to provide expert level application engineering to achieve this goal.
