Product Description High-performance drill for high-speed, heavy-duty drilling of high-strength and stainless steel sheets.TiAlN coating increases tool life and reduces cutting forces.Properties and benefits:1.Cross-point sharpening: thinning of the tip of the drill. Allows easy self-centering of the drill bit on the smoothest surfaces. Greatly reduces the axial effort required.2.TiAlN coating: TiAlN base, thickness 2/4μm, hardness 3000HV, friction coef 0.4, hot hold 900°C. Protects against abrasion, oxidation, adhesion. Increases service life. Reduces cutting forces with cutting edge protection and Better chip slip. Versatile uses.3.3-flat tail: cylindrical tail with 3 120° flats for 3-bit drill chuck. Allows maximum transmission of the couple. Avoids the rotation of the drill bit in the mandrel. Specially suitable for unlocking holes.4.High-speed steel 5% Cobalt: HSS substrate enriched with 5% Cobalt. Better heat resistance (toughness, cutting acuity).Technical Specifications: Drill Diameter Drill Diameter d3Handle Diameter or CMTotal LengthTrimmed Length124665422048755230410100773741010077Features: Application: Widely Uesd: Related Surface Treatment: Related Packaging:
