Product Description
Why choose this Cobalt Step Drill Bit Set?
FOUR SPIRAL FLUTE - Four cutting blades design guarantees a faster and smoother cutting, allows swarf escape easily.
TiAlN COATING- With 89HRC surface hardness, harder materials can be cut and higher cutting speeds can be achieved.
M35 COBALT HSS STEP DRILL - Prefect for Stainless Steel/Metal Sheet/Wood/Plastic/Aluminum Sheet/Copper and other metal sheets.
135°CUTTING ANGLE - The increased angle of the drill tip is more suitable for drilling hard materials than 118°. The larger the included angle, the smaller the self-wear and the larger the stress area.
Specifications:
1/4"-3/4" (9 step size) : 1/4", 5/16", 3/8",7/16", 1/2", 9/16", 5/8", 11/16", 3/4"
1/8"-1/2" (13 step size) : 1/8",3/32", 3/16", 7/32", 1/4", 9/32", 5/16", 11/32", 3/8", 13/32", 7/16",15/32",1/2"
Includes 3 bits with 1/8" - 1/2", 1/4" - 3/4", 3/16" - 7/8"

Product Information
- FOUR CUTTING BLADE UP TO 4X FASTER - Ordinary step drills are prone to deflection during cutting, four cutting blade design guarantees a faster and smoother cutting, allows swarf escape easily.
- ULTRA TiAlN COATING UP TO 10X LONGER LIFE - TiAlN coating has excellent characteristics. As a new coating material, which can minimize the wear of the drill bit during each drilling process.
- M35 COBALT PREMIUM STEP BIT - M35 steel is a kind of high speed steel containing cobalt, which has the characteristics of high red hardness, high wear resistance and sintering resistance. M35 cobalt can obtain high hardness (HRC 64-66) through proper heat treatment.
- 34 TOTAL STEP SIZE - Includes 3 bits with 1/8" - 1/2", 1/4" - 3/4", 3/16" - 7/8". Perfect for Stainless Steel/Metal Sheet/Wood/Plastic/Aluminum Sheet/Copper and other metal sheets.
- RELIABLE BRAND - Bring you the pleasure of cutting butter blocks. If the hex shank snap off, MABLEVI will repair and replace any defect, without charge, and without waiting.
