## Summary description

DeWalt DT4907-QZ is a single twist drill bit supplied in a blister pack. It is designed for right-hand rotation drilling and intended for use with standard drills for creating holes. The pack contains one drill bit; suitable for general drilling tasks where a conventional twist bit is required.

## Long description

DeWalt DT4907-QZ is a single twist drill bit supplied in a blister pack, designed for right-hand rotation drilling with standard drills. This 5.5 mm diameter bit, with a total length of 93 mm, is intended for creating clean holes in a range of metals including steel, stainless steel, cast iron and bronze. The bit is made from cobalt-alloyed high speed steel and features an optimised tip and flute geometry for faster penetration and controlled chip removal.
Advantages
The 5% cobalt content increases hardness and maintains a sharper cutting edge for extended life compared with standard HSS-R bits. A ‘no-walk’ tip provides easier surface penetration and reduces walking on initial contact, enabling more accurate, burr-free holes. The bit’s optimised flute geometry accelerates penetration speed and helps remove debris quickly to reduce heat build-up during drilling. For diameters 5 mm and above, a three-sided anti-slip shank improves grip in the drill chuck and size indicators are positioned away from abrasion for easy readability.
Suitable for
Portable and stationary drilling in high-alloy steels and stainless steels (up to 1100 N/mm² tensile strength)
Drilling of cast iron, bronze and general metalwork
Piercing welded seams and heat- or acid-resistant steels
Applications requiring accurate, burr-free holes and improved bit life
Key specifications
Type: Twist drill bit, right-hand rotation
Diameter: 5.5 mm
Length: 93 mm (total)
Material: 5% cobalt-alloyed high speed steel
Tip: No-walk, optimised geometry for faster penetration
Shank: Hexagonal / three-sided anti-slip shank (for diameters 5 mm and above)

Pack quantity: 1 piece (blister)
How to use
Install the DeWalt DT4907-QZ in a compatible drill chuck ensuring the hex shank is seated securely to prevent slippage. Select an appropriate drill speed and use cutting fluid for harder alloys or stainless steel to reduce heat and extend tool life. Begin drilling with steady pressure, allowing the no-walk tip to establish the hole before increasing feed. Withdraw occasionally to clear chips when drilling deeper holes, and allow the bit to cool if excessive heat is observed.
Usage recommendations
Use this bit for metalworking tasks where durability and accuracy are required. For materials with tensile strengths up to 1100 N/mm², use moderate speeds with cutting fluid. Replace the bit when wear degrades the cutting edge to maintain hole quality and avoid excessive force that could cause breakage.
