YG-1’s SV-Point spade drill inserts are said to provide longer tool life at higher spindle speeds and feeds than conventional spade drills. The inserts are designed for a range of applications and materials including steel, stainless steel and cast iron.

The SV-Point’s H-Coating offers high heat and wear resistance. Sinusoidal thinning edge enables smooth cutting and improves centering, while a positive rake angle improves hole finish. Imparting low thrust force, the tool is an effective option for underpowered machines, the company says. 

Three material options are available, including: 

  • Super Cobalt (T15), designed for improved tool life and performance compared to standard high speed steel inserts, with a size range of 9.5 to 114.3 mm;
  • Premium Cobalt (M48), providing extended tool life compared to T15 in harder materials, with a size range of 9.5 to 114.3 mm; and 
  • Carbide C5 (P40), designed for longer tool life and faster speeds and feeds in rigid setups, with a size range of 9.5 to 47.6 mm.


  • 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.

  • Taking The Fear Out Of Hard Turning

    To make the transition to hard turning, you'll need to switch from carbide to CBN inserts, but that is easier (and more economical) than you might think. It's making the jump to much higher surface speeds that might scare you off. It needn't. Here's why.

  • Drill And Bore With A Face Mill

    Cutting holes by interpolating a face milling cutter may be a better process choice for many rough and even finish boring operations. Software improvements and better cutter designs allow expanding use of the versatile face mill for hole making.
