4mm Brad Point Boring Bit For Clean Drilling

4mm x 57mm brad point boring bit is a dedicated boring tool sized for 4mm holes, so it creates a consistent diameter suitable for precise woodworking layouts. The 57mm long design reaches deeper drilling locations, which helps when working through thicker stock or stacked components. This bit is a right hand pattern, so it rotates clockwise in compatible machines, aligning with standard right hand boring heads. The cutting end uses a brad point geometry, so the point starts the hole accurately before the cutting lips engage, helping keep holes on location. An Amana Tool brand build ties this bit to a professional tooling line, giving installers and shop users a familiar specification. The shank is sized for dedicated boring equipment, so the working end is supported by a solid interface while drilling.

Key Boring Bit Details That Support Precise Work

• The 4mm diameter cutting end drills accurately sized holes, which is useful when hole fit needs to match 4mm hardware or layout jigs without constant reaming or adjustment.
• The 57mm overall length lets the bit reach deeper drilling positions, which helps when boring through thicker panels or when fixturing keeps the spindle slightly higher.
• The right hand configuration means the bit rotates clockwise, which aligns with right hand boring heads and helps keep setup consistent across multiple spindles.
• The brad point cutting geometry centers the bit as it enters the material, which helps limit wandering and supports accurate hole placement on visible surfaces.
• The shank is designed for dedicated boring equipment, which gives the bit a stable grip in the spindle so the cutting edge tracks straighter during repeated drilling.
• The Amana Tool branding identifies the bit as a woodworking-focused cutter, which helps shops match this bit to other Amana Tool boring and drilling tools they already use.

Boring And Drilling Setup Details For This Bit

This brad point boring bit is intended for use in boring machines that accept a 10mm shank, so it fits directly into those spindles without adapters. The same cutting geometry is available on a 3/8 inch shank version for drill presses, so shops can match tooling across machines when needed. This bit is not for use in portable drills or routers, so it stays in stationary equipment where feed direction and alignment are controlled. The right hand clockwise rotation is matched to right hand boring heads, so spindle direction and feed can stay consistent from job to job. The 4mm diameter and 57mm length combination allows repeatable plunge depths, so depth stops can be set once and reused across multiple workpieces.

Using This Boring Bit In Woodworking Production

Where This 4mm Boring Bit Performs Best

The 4mm x 57mm brad point boring bit works in boring machines equipped for 10mm shank tools, so it suits line boring and dedicated drilling stations using that spindle standard. Its 4mm cutting diameter supports layouts that rely on small dowel or fastener pilot holes, so hole spacing driven by boring heads can stay tight and consistent. The 57mm long format provides enough reach for panels and parts where the drilling depth is more substantial, so a single setup can handle both shallow and deeper holes. The brad point tip locates precisely on layout marks, so operators can position workpieces under the spindle and trust the point to enter on the mark. Right hand clockwise rotation pairs with common machine rotation patterns, so this bit can run alongside other right hand tools on multi-spindle equipment.

Details That Support Repeatable Boring Accuracy

The brad point cutting design gives this bit a centered point ahead of the main cutting edges, so the point contacts the material first and stabilizes the entry, which reduces walking and supports straight holes. The 10mm shank provides a solid, round mounting surface in compatible boring machine chucks or collets, so the tool stays concentric and helps maintain diameter accuracy over multiple cycles. Right hand rotation ensures that the cutting edges engage the work as the spindle turns clockwise, which matches the way many boring heads are timed and reduces the need to change motor direction. The 4mm size remains consistent from bit to bit, so shops can set up fences, stops, and templates around this diameter for interchangeable production runs. The dedicated note that this bit is not for portable drills or routers keeps it in controlled-feed machines, which supports cleaner entry and exit quality on cabinet parts and furniture components.
