YG-1's SV-Point Spade Drill Enables Higher Feeds and Speeds

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.
