Precision Dormer has expanded its Hydra solid carbide replaceable-head drilling program range, which is an alternative to solid carbide drills. Two head types are available. The R960 was developed specifically for drilling operations in stainless steel and cast iron, but is also well-suited for use in titanium and nickel, the company says. The R950, available in diameters as large as 42.0 mm, is designed for machining carbon and alloy steels.
 
Both heads incorporate a self-centering, 140-degree, four-facet split point said to ensure low thrust forces through the drilling cycle and promote consistent high performance. The heads are designed to be changed quickly, without removing the body from the spindle. Each head features a high speed steel construction and is available with a range of drill bodies to support drilling depths of 3×D (H853), 5×D (H855) and 8×D (H858). One body can accommodate multiple head sizes with no compromise on structural integrity, the company says.

  • Rolling Threads Has Advantages

    With macros and canned cycles resident in the CNC on most contemporary turning centers, single point turning of OD threads can seem like almost a default process decision. However, for numerous applications, OD thread rolling has inherent advantages as an alternative to cutting threads.

  • Rigid Tapping--Sometimes You Need A Little Float

    One of the most common methods of tapping in use today on CNC machines is 'rigid tapping' or 'synchronous feed tapping.' A rigid tapping cycle synchronizes the machine spindle rotation and feed to match a specific thread pitch. Since the feed into the hole is synchronized, in theory a solid holder without any tension-compression can be used.

  • Successful Application Of Ceramic Inserts

    Applying ceramic inserts is not a simple substitution of one cutting tool material for another. There are significant process considerations that shops should examine carefully in order to realize performance and tool life expectations from ceramic inserts. Here's a look at some of the ways they are used.
