SPHINX SPIREC High Speed Steel Micro Center Drills Made In Switzerland

Center Pivot Drills are similar to regular Spirec spiral drills but have a shorter flute for added rigidity. When drilling very small holes it is often a problem to drill a suitable center. These SPHINX SPIREC High Speed Steel Micro Center Drills are ideal for producing true center holes.
The Shank diameter is 1.00 mm for all drill sizes up to 0.50 mm, drills over 0.50 mm have shank diameter of 1.5 mm.
