Drill bit YATO YT-44881, single piece
YATO YT-44881 is a single-piece high-speed steel (HSS) drill bit designed for professional drilling in high-grade stainless steel, structural steel, INOX and cold-rolled steel. Supplied as an individual replacement bit, it fits standard drill chucks and is intended for workshop, construction and repair tasks where a robust, precision bit is required.
The HSS 6542 construction provides faster cutting and improved resistance to wear and dulling while preserving drill geometry. A 135° split point cross-blade design enables drilling without prior scoring and ensures accurate centring. Ground surfaces and edges made to DIN 338 standard deliver precise hole dimensions. The bit dissipates heat rapidly during hard-steel drilling and the reduced friction surface lowers adhesion of swarf and filings. A 1/4" hex (6.3 mm) shank allows quick and secure fitting in compatible chucks and holders.
Install the YATO YT-44881 drill bit into a compatible drill chuck or quick-change hex holder, ensuring it is securely clamped. Use appropriate cutting speeds and coolant or cutting oil when drilling stainless and hard steels to reduce heat buildup. Apply steady pressure and allow the split point to self-centre; retract periodically to clear chips when drilling deep holes. After use, clean swarf from the flutes and store the bit dry to avoid corrosion.
For best results when drilling stainless and structural steels, use reduced feed rates and cutting fluids. Match drilling speed to material thickness and hardness; avoid excessive speeds that may overheat the bit and shorten tool life.
