## Summary description

DeWalt DT4912 twist drill bit designed for drilling with right-hand rotation. Supplied as a single piece in a blister pack, this drill bit fits standard rotary drills and is intended for general drilling tasks. The product listing specifies proper use as a drill and identifies the bit type as a twist drill bit.

## Long description

The DeWalt DT4912 twist drill bit is a single-piece, right-hand rotation bit supplied in a blister pack for standard rotary drills. Designed for general drilling tasks, this HSS-Co cobalt twist drill bit is suitable for drilling a variety of ferrous and non-ferrous metals, including high-alloy steels and stainless materials. The bit features an optimised tip and flute geometry that improves penetration speed and chip evacuation while reducing heat build-up during operation.
Advantages
The 5% cobalt composition maintains a sharper cutting edge and extends tool life compared with standard HSS-R bits. A ‘‘no-walk’ tip enables easier surface penetration and more accurate, burr-free holes from 5 mm diameter and above. Size indicators are positioned away from abrasion zones for easy readability. The three-sided no-slip shank (on diameters from 5 mm) improves grip in the chuck to reduce spinning, and a reinforced central core increases fracture stability for freehand drilling on larger diameters. Overall geometry improvements deliver faster drilling and more efficient chip removal.
Suitable for
Portable and stationary drilling of high-alloy and heat-resistant steels
Drilling stainless steels, chrome-nickel alloys and welded seams
Working on cast iron, bronze and other metals with tensile strength up to 1100 N/mm²
General metalworking tasks requiring durable, accurate holemaking
Key specifications
Type: Twist drill bit (right-hand rotation)
Material: High-speed steel with 5% cobalt (HSS-Co)
Packaging: Single piece in blister pack
Tip: No-walk tip for improved centring and reduced burrs (effective from 5 mm)
Shank: Three-sided anti-slip shank for improved chuck grip (from 5 mm)
Core design: Reinforced central core for improved fracture stability (from ~4.8 mm)
Performance: Optimised flute and tip geometry for faster penetration and improved chip evacuation
How to use
Fit the DT4912 twist drill bit securely into the drill chuck, ensuring the three-sided shank (if present for the diameter) seats correctly to prevent slippage. Select appropriate rotational speed and feed rate for the material being drilled; lower speeds and steady pressure are recommended for hardened or stainless steels. Use cutting fluid or coolant when drilling high-alloy or heat-resistant steels to reduce heat and improve tool life. Begin drilling with light pressure to allow the no-walk tip to locate the hole, then apply steady, even pressure until the hole is completed.
Usage recommendations
For best results when drilling high-alloy and stainless steels, use suitable cutting fluid, avoid excessive speed that generates heat, and periodically withdraw the bit to clear chips. Inspect the bit before use and replace when the cutting edge shows significant wear to maintain hole quality and reduce the risk of breakage.
