Migiwata 1.0-10mm Straight Shank Titanium Coated High Speed Steel Twist Drill Bits Set of 19pcs in 19 Sizes for General Purpose

Color:Gold 19 This Migiwata twist drill bits are designed for general purpose. They can be used in drilling sheet iron, aluminum, wood, plastic and most other materials for household, DIY work, etc. Coated with titanium nitride, a very hard ceramic material, the cutting life of twist drill bits will be extended by three and more times than ordinary high-speed steel bits. Even after sharpening, the leading edge of coating still provides improved cutting and lifetime. Each piece of twist drill bit comprises a cutting point at the tip of a cylindrical shaft with helical flutes. The helical flute will lift swarf out of the hole to keep drilling work going on. The cylindrical shaft or shank of each twist drill bit is straight, which is compatible with 3-jaw standard power drill and can also be held in a collet chuck (which must be tightened), particularly for smaller sizes. Additionally, straight shank is very accurate centering compared with other shank types like hex shank, brace shank, etc. Specification: Material: high speed steel Color: golden Coating: Titanium Usage: general purpose What you get: 1.0mm twist drill bit x 1pc 1.5mm twist drill bit x 1pc 2.0mm twist drill bit x 1pc 2.5mm twist drill bit x 1pc 3.0mm twist drill bit x 1pc 3.5mm twist drill bit x 1pc 4.0mm twist drill bit x 1pc 4.5mm twist drill bit x 1pc 5.0mm twist drill bit x 1pc 5.5mm twist drill bit x 1pc 6.0mm twist drill bit x 1pc 6.5mm twist drill bit x 1pc 7.0mm twist drill bit x 1pc 7.5mm twist drill bit x 1pc 8.0mm twist drill bit x 1pc 8.5mm twist drill bit x 1pc 9.0mm twist drill bit x 1pc 9.5mm twist drill bit x 1pc 10.0mm twist drill bit x 1pcPlastic case x 1pcWarranty : Within 90 days product quality is not completely satisfied, please CONTACT US, 100% refund.
