Key Product Selling Points
- Self-starting step drill design eliminates the need for pilot holes, ensuring precision in sheet metals, alloys, and plastics (up to 4mm thick).
- Titanium-coated HSS construction enhances durability, reduces friction, and extends bit life.
- Clearly marked 2mm graduations enable precise depth control and hole sizing up to 22mm.
- 12mm shank ensures secure compatibility with standard drill chucks.
- Produces clean, burr-free holes for professional-grade results in thin materials.
Detailed Product Description
This titanium-coated high-speed steel (HSS) step drill is engineered for precision drilling in sheet metals, alloys, and plastics. The self-starting tip allows immediate engagement without pre-drilling, while the 2mm laser-etched graduations provide accurate depth guidance for holes ranging from 4mm to 22mm. The titanium coating minimizes heat buildup and wear, ensuring smooth performance even during prolonged use. Ideal for HVAC, automotive, or DIY projects, this drill bit combines versatility with industrial-grade durability.
Direction for Use
Insert the 12mm shank securely into a compatible drill chuck. Align the self-starting tip perpendicular to the material surface. Begin drilling at a low speed, gradually increasing as the bit engages. Use the 2mm graduations to monitor hole depth and adjust as needed. For metals, apply a cooling lubricant to reduce heat and prolong bit life.
Materials
Titanium-coated HSS, precision-machined 12mm shank.
Product Warnings
Always wear safety goggles and gloves during operation. Avoid excessive pressure to prevent bit breakage or material deformation. Store in a dry, cool place to prevent corrosion. Not suitable for masonry, hardwood, or thick metals. Keep out of reach of children.
