Dormer Drill Bit HSS Set 21Pcs. No.3 1/16-3/8″

TiN-Tip Performance – The Titanium Nitride coating on the cutting zone reduces friction and heat buildup, allowing for faster drilling speeds and significantly longer tool life.

Precision Increments – Includes a full range of sizes from 1/16″ to 3/8″ in 1/64″ steps, providing the exact diameter needed for precise mechanical assembly and tapping operations.

Self-Centering Split Point – Features a 118° split point geometry that eliminates the need for a center punch by preventing the bit from “walking” or “skating” upon contact with the material.

Efficient Chip Removal – Engineered with optimized flute geometry to ensure rapid evacuation of swarf, reducing the risk of bit breakage and ensuring a smoother hole finish.

Industrial Versatility – Highly effective for drilling a wide variety of materials, including carbon and alloy steels, cast iron, and non-ferrous metals.

Rugged “Selector” Case – Housed in a durable, impact-resistant plastic index case that stores bits in a tiered, upright position for quick identification and easy access on the job.

Professional Standard – Manufactured to rigorous industrial standards, ensuring consistent performance and diameter accuracy across all 21 pieces.
