M35 Cobalt HSS: Super tough, resistant to wear, high thermal threshold. Designed for tackling tough materials like stainless steel and other high-performance alloys. Please ensure sufficient lubrication and cooling in extensive uses.

Cobalt coating helps with wear and thermal. Please be reminded that the countersinking performance will not be impacted even if coatings are worn down. The wear and tear of coating is normal and the performance relies on hardness of the countersink bit itself.

PRO compatibility for professional machinist and DIY enthusiasts: Round shank can be fitted with hand drills and bench drills. We recommend using bench drills for optimal results when working with hard alloys.

PREMIUM QUALITY - The center and spotting drills are made of durable high speed steel for providing wear resistance and remove chippings clearly and long service life.

PRODUCT FEATURE - The bits with the 60°countersink angle have double ended design.Center drill bit can be used to process the centering hole and countersink of general material.

SPIRAL FLUTE - The combined center drill bits are design with spiral groove, decreasing friction and heat, which can help clear chips and debris away from the bit quickly. It is a useful tool for DIY amateur.

High-speed steel tools are good for most general purpose applications, offering a combination of hardness and toughness for wear resistance

Black oxide treatment adds lubricity and creates small pockets on the surface of the tool that act to hold coolant near the cutting edge

Round shanks allow use with a wide variety of toolholding systems

✅【Universal Compatibility】The T-4241 step drill bit can provide fast and smooth drilling on holes of different diameters in steel, aluminum, wood, plastic boards, etc. (NOTE: the board must be thinner than the height of the step drill).

✅【Quick Change】The 1/4 inch hex shank is compatible with impact resistant power tools and allows for quick, easy, and convenient step drill switching.

✅【Hss 30+ Sizes】Drilling Sizes Include: 13 Step Drill Bits (1/8, 5/32, 3/16, 7/32, 1/4, 9/32, 5/16, 11/32, 3 /8, 13/32, 7/16, 15/32, 1/2-inch) 6-step drill bits (3/16, 1/4, 5/16, 3/8, 7/16, 1/2-inch) and 12 step drills (3/16, 1/4, 5/16, 3/8, 7/16, 1/2, 9/16, 5/8, 11/16, 3/4, 13/16, 7 /8") different sized holders ensure compatibility with 1/4, 3/8 and 1/2" chuck sizes to suit your normal needs.
